78 Best Sights in Philadelphia, Pennsylvania

Nearly sequestered from public view for a century in Lower Merion, Pennsylvania, this legendary collection of 19th- and 20th-century masterpieces made world headlines when it relocated to this spectacular new home in May 2012. While the statistics are impressive—81 Renoirs, 69 Cézannes, 59 Matisses, 46 Picassos, 7 Van Goghs, 6 Seurats (and many more)—almost more inspiring is this soaring marble-and-glass museum. Largely thanks to a brilliant modernist setting, the greatness of this collection of art is only now revealed, due to a new design that lends a sense of intimacy between viewer and object, while at the same time increasing one's appreciation of capital-A art.

The collection was amassed (in the 1920s and 1930s) thanks to the millions Dr. Albert C. Barnes made in pharmaceuticals. As a theorist, he wanted to help people "see as an artist saw" and to do this, he created for each gallery wall an "ensemble" of mirror-like symmetry: a Matisse could hang side-by-side with a Goya, above an African sculpture, and below a Old Master sketch and a French tin shoe buckle. As his will decreed that nothing could be changed, everything had to be transported—lock, stock, and Modigliani—to this new showcase.

Warmed by walls of tawny-colored Negev sandstone, centered around an enormous "Light Court"—the perfect place for gallery-goers to reflect on art—and entered through a narrow "mood tube" of reflecting pools and tall trees, the design of architects Tod Williams and Billy Tsien may be minimalist in style but remains mellow in impact. Inside, an interior garden, art library, restaurant, two classrooms, and café are winningly used as buffer zones to the rooms hung with the core collection.

Highlights include some of the most fabled paintings of Impressionist, Post-Impressionist, and Modern art, including Cézanne's The Card Players, Georges Seurat's Models, Van Gogh's Postman Roulin, Monet's Studio Boat, Matisse's Joy of Life and La Danse mural, Renoir's The Artist's Family, and Picasso's Acrobat and Young Harlequin. Thanks to a new lighting system, the art looks so fresh that it seems the artists had just put down their palettes. It is safe to say that most museum-goers will find this new Barnes Foundation a work of art in itself. For information about the museum's packed calendar of classes, lectures, and concerts, see the website. It's wise to make a reservation in advance.

Topped by a 37-foot bronze statue of William Penn, City Hall was Philadelphia's tallest building until 1987; you can study the trappings of government and also get a panoramic view of the city here. With 642 rooms, it's the largest city hall in the country and the tallest masonry-bearing building in the world: no steel structure supports it. Designed by architect John McArthur Jr., the building took 30 years to build (1871–1901) and cost taxpayers more than $23 million. The result has been called a "Victorian wedding cake of Renaissance styles." Placed about the facade are hundreds of statues by Alexander Milne Calder, who also designed the statue of William Penn at the top. Calder's 27-ton cast-iron statue of Penn is the largest single piece of sculpture on any building in the world.

Not only the geographic center of Penn's original city plan, City Hall is also the center of municipal and state government. Many of the magnificent interiors—splendidly decorated with mahogany paneling, gold-leaf ceilings, and marble pillars—are patterned after the Second Empire salons of part of the Louvre in Paris. On a tour each weekday at 12:30 you can see the Conversation Hall, the Supreme Court of Pennsylvania, the City Council chambers, and the mayor's reception room. You can attend the frequently heated City Council meetings, held each Thursday morning at 10.

To top off your visit, take the elevator from the seventh floor up the tower to the observation deck at the foot of William Penn's statue for a 30-mile view of the city and surroundings. The elevator holds only six people per trip and runs every 15 minutes; the least crowded time is early morning. The 90-minute building tour, including a trip up the tower, steps off weekdays at 12:30. The tour office is in Room 121.

The grounds take up an entire block, and its unique history, impressive architecture, and the guides who spin a good yarn combine to make Cliveden perhaps the best visiting experience of the historic Germantown homes. The elaborate country house was built in 1767 by Benjamin Chew (1722–1810), a Quaker and chief justice of the colonies, and something of a fence-straddler during the Revolution. Cliveden was at the center of the Battle of Germantown, occupied by British troops, and the walls still bear the marks of American cannon fire. Except for a brief period of time in the late 1700s when it was owned by a privateer (legalized piracy), the house remained in the Chew family until 1972, when it was donated to the National Trust for Historic Preservation. The original house has been completely opened to the public. A shining example of Georgian style, it has Palladian windows and an elegant entrance hall. The family-owned furniture includes a mahogany sofa by Thomas Affleck and looking glasses by James Reynolds. An elaborate reenactment of the Battle of Germantown is held here annually on the first Saturday in October. The house, on 6 acres, can be seen on a 45-minute guided tour.

This open-air Colonial marketplace, extending from Pine Street to Lombard Street, is a reminder of the days when people went to central outdoor markets to buy food directly from farmers. It was first established as New Market in 1745. George Washington was among those who came here to buy butter, eggs, meat, fish, herbs, and vegetables. The Head House, a boxy building with a cupola and weather vane, was built in 1803 as the office and home of the market master, who tested the quality of the goods. Today, every Sunday from May through December, it is the site of a farmers' market, featuring about two dozen vendors selling everything from honey and flowers to pickles and pastries. On some summer weekends the square also is home to a crafts-and-fine-arts fair featuring the work of more than 30 Delaware Valley artists.

The birthplace of the United States, this redbrick building with its clock tower and steeple is one of the nation's greatest icons. America's most historic building was constructed in 1732–56 as the Pennsylvania State House. What happened here between 1775 and 1787 changed the course of American history—and the name of the building to Independence Hall. The delegates to the Second Continental Congress met in the hall's Assembly Room in May 1776, united in anger over the blood that had been shed when British troops fired on citizens in Concord, Massachusetts. In this same room George Washington was appointed commander in chief of the Continental Army, Thomas Jefferson's eloquent Declaration of Independence was signed, and later the Constitution of the United States was adopted. Here the first foreign minister to visit the United States was welcomed; the news of Cornwallis's defeat was announced, signaling the end of the Revolutionary War; and, later, John Adams and Abraham Lincoln lay in state. The memories this building holds linger in the collection of polished muskets, the silver inkstand used by delegates to sign the Declaration of Independence, and the "Rising Sun" chair in which George Washington sat. (After the Constitution was adopted, Benjamin Franklin said about the sun carving on the chair, "I have the happiness to know that it is a rising and not a setting sun.")

In the East Wing—attached to Independence Hall by a short colonnade—you can embark on free tours that start every 15 to 20 minutes and last 35 minutes. Admission is first-come, first-served; pick up free, timed tickets from the visitor center to avoid waiting in line. The West Wing of Independence Hall contains an exhibit of the national historical park's collection of our nation's founding documents: the final draft of the Constitution, a working copy of the Articles of Confederation, and the first printing of the Declaration of Independence.

In front of Independence Hall, next to the statue of George Washington, note the plaques marking the spots where Abraham Lincoln stood on February 22, 1861, and where John F. Kennedy delivered an address on July 4, 1962. With Independence Hall in front of you and the Liberty Bell behind you, this is a place to stand for a moment and soak up a sense of history. From March through December and on major holidays, free, timed tickets from the Independence Visitor Center are required for entry. Tickets also can be reserved online (www.recreation.gov).

It's more Naples than Philadelphia: vendors crowd the sidewalks and spill out onto the streets; live crabs wait for the kill, while it's too late for the lambs and pigs displayed in butcher-shop windows; fresh, seasonal produce is piled high. The market dates to the turn of the last century, when it was founded by Italian immigrants. You'll find fresh pastas, cheeses, spices, meats, fruits and vegetables, and dry goods and kitchen equipment, as well as junky dollar-stores and funky boutiques. These days the market has become more diversified, with the addition of several Mexican grocers, a natural foods grocer, taquerias, a sandwich shop popular with foodies, and several coffee spots.

The bell fulfilled the words of its inscription when it rang to "proclaim liberty throughout all the land unto all the inhabitants thereof," beckoning Philadelphians to the State House yard to hear the first reading of the Declaration of Independence. Ordered in 1751 and originally cast in England, it cracked during testing and was recast in Philadelphia by Pass and Stow two years later. To keep it from falling into British hands during the Revolution—they would have melted it down for ammunition—it was spirited away by horse and wagon to Allentown, 60 miles to the north. The Liberty Bell is the subject of much legend; one story says it cracked when tolled at the funeral of Chief Justice John Marshall in 1835. Actually, the bell cracked slowly over a period of years. It was repaired but cracked again in 1846 and was then forever silenced. It was called the State House Bell until the 1830s, when a group of abolitionists adopted it as a symbol of freedom and renamed it the Liberty Bell.

After more than 200 years inside Independence Hall, the bell was moved to a glass-enclosed pavilion for the 1976 Bicentennial, which for many seemed an incongruous setting for such a historic object. In mid-2003 it once again moved to another glass-enclosed pavilion with redbrick accents. This time, great care was taken to improve access and viewing of its former home at Independence Hall, which is seen against the backdrop of the sky—rather than 20th-century buildings. The Liberty Bell complex houses a bell chamber, an interpretive exhibit area with historic displays and memorabilia, and a covered area for waiting in line.

During construction for the bell's current home, the foundation and other archaeological remains of The President's House, the home of the nation's chief executives before the capital shifted to Washington, D.C., were discovered, as well as evidence of slaves owned by President George Washington who lived there during his time in office. A new permanent installation includes a series of video panels focusing on the stories of the nine enslaved African Americans, as well as glass panels through which you can view the remains of the structure's foundation.

The former John Wanamaker department store, this building is almost as prominent a Philadelphia landmark as the Liberty Bell. Wanamaker began with a clothing store in 1861, and became one of America's most innovative and prominent retailers. The massive building, which occupies a city block with grace, was designed by the noted Chicago firm of D. H. Burnham and Company. Its focal point is a 2,500-pound statue of an eagle, a remnant of the 1904 Louisiana Purchase Exposition in St. Louis. "Meet me at the Eagle" remains a popular way for Philadelphians to arrange a rendezvous. The store's 30,000-pipe organ—the largest ever built—is used for free concerts Monday, Tuesday, Thursday, and Saturday at noon and 5:30, and Wednesday and Friday at noon and 7. They offer a spectacular holiday light show between Thanksgiving and New Year as well.

This 160,000-square-foot museum brings the U.S. Constitution alive through a series of highly interactive exhibits tracing the development and adoption of the nation's landmark guiding document. The heart of the sprawling museum, The Story of We the People, takes you from the American Revolution through the Constitution's ratification to major events in the nation's constitutional history, including present-day events like the inauguration of President Barack Obama, Hurricane Katrina, and the recent economic crisis. Later, you can play the role of a Supreme Court justice deciding an important case, and walk among the framers in Signers' Hall, where you can decide whether to add your signature to the list of Founding Fathers. The facility has 100-plus exhibits, plays host to many events with major historians, authors, and political figures, and also houses the Annenberg Center for Education and Outreach, a hub for constitutional education efforts that is not open to the public.

This High Victorian Gothic structure is a work of art in itself. Designed in 1876 by the noted, and sometimes eccentric, Philadelphia architects Frank Furness and George Hewitt, the multicolor stone-and-brick exterior is an extravagant blend of columns, friezes, and Richardsonian Romanesque and Moorish flourishes. The interior is just as lush, with rich hues of red, yellow, and blue and an impressive staircase. The nation's first art school and museum (founded in 1805) displays a fine collection that ranges from the Peale family, Gilbert Stuart, Benjamin West, and Winslow Homer to Andrew Wyeth and Red Grooms. Fox Hunt by Winslow Homer, and The Artist in His Museum by Charles Willson Peale, are just a few notable works. The academy faculty has included Thomas Sully, Charles Willson Peale, and Thomas Eakins. The latter painted what is now the museum's most prized work, The Gross Clinic, a dramatic depiction of Samuel D. Gross, a celebrated 19th-century surgeon, presiding over an operation under a skylighted roof; the masterwork is co-owned with the Philadelphia Museum of Art, and is displayed for six months at a time at each institution.

Supplementing the permanent collection are constantly changing exhibitions of sculptures, paintings, and mixed-media artwork in the adjacent Samuel M. V. Hamilton Building; the 11-story facility, which opened for the academy's 200th anniversary, is also the home to the Sculpture Study Center, which offers changing displays from the permanent collection, classrooms, group and private studios for more than 300 students, and Portfolio, the museum's gift shop. The 1400 block of Cherry Street, which runs between the two buildings, is a pedestrian plaza featuring Paint Torch, a 53-foot-tall sculpture of a paintbrush by Claes Oldenburg, a three-part serpentine bench, and outdoor seating.

The city's premier cultural attraction is one of the country's leading museums. One of the greatest treasures of the museum is the building itself. Constructed in 1928 of Minnesota dolomite, it's modeled after ancient Greek temples but on a grander scale. The museum was designed by Julian Francis Abele, the first African-American to graduate from the University of Pennsylvania School of Architecture. You can enter the museum from the front or the rear; choose the front and you can run up the 99 steps made famous in the movie Rocky.

Once inside, you'll see the grand staircase and Saint-Gaudens's statue Diana; she formerly graced New York's old Madison Square Garden. The museum has several outstanding permanent collections: the John G. Johnson Collection covers Western art from the Renaissance to the 19th century; the Arensberg and A. E. Gallatin collections contain modern and contemporary works by artists such as Brancusi, Braque, Matisse, and Picasso. Famous paintings in these collections include Van Eyck's St. Francis Receiving the Stigmata, Rubens's Prometheus Bound, Benjamin West's Benjamin Franklin Drawing Electricity from the Sky, van Gogh's Sunflowers, Cézanne's The Large Bathers, and Picasso's Three Musicians. The museum has the world's most extensive collection of works by Marcel Duchamp, including the world-famous Nude Descending a Staircase and The Bride Stripped Bare by Her Bachelors, Even. Among the American art worth seeking out is a fine selection of works by 19th-century Philadelphia artist Thomas Eakins, including The Gross Clinic, which the museum co-owns with the Pennsylvania Academy of the Fine Arts.

Perhaps the most spectacular objects in the museum are entire structures and great rooms moved lock, stock, and barrel from around the world: a 12th-century French cloister, a 16th-century Indian temple hall, a 16th-century Japanese Buddhist temple, a 17th-century Chinese palace hall, and a Japanese ceremonial teahouse. Among the other collections are costumes, Early American furniture, and Amish and Shaker crafts. An unusual touch—and one that children especially like—is the Kienbusch Collection of Arms and Armor.

The Ruth and Raymond G. Perelman Building, across the street in the former Reliance Standard Life Insurance Building, is home to the museum's permanent collection of photography, costume, and contemporary design.

Friday evenings feature live jazz and world music performances in the Great Hall. The museum has a fine restaurant and a surprisingly good cafeteria now under the management of well-known restaurateur Stephen Starr. A short stroll away is the Fairmount Waterworks and Boathouse Row, as well as a path well used by bikers and joggers that connects the museum to Center City's Fitler Square neighborhood.

The market is nothing short of a historic treasure, and a food heaven to Philadelphians and visitors alike. One floor beneath the former Reading Railroad's 1891 train shed, the sprawling market has more than 75 food stalls and other shops, selling items from hooked rugs and handmade jewelry to South American and African crafts. Here, amid the local color, you can sample Bassett's ice cream, Philadelphia's best; down a cheesesteak, a hoagie, a bowl of snapper soup, or a soft pretzel; or nibble Greek, Mexican, Thai, and Indian specialties. From Wednesday through Saturday the Amish from Lancaster County cart in their goodies, including Lebanon bologna, shoofly pie, and scrapple. Many stalls have their own counters with seating; there's also a central eating area. An open kitchen offers regular demonstrations by some of the region's top chefs. You can also take a guided Market Tour on Wednesdays and Saturdays at 10 am. The entire building is a National Historic Landmark, and the train shed is a National Engineering Landmark. The market is easily accessible by SEPTA's Blue Line subway, regional rail, and bus.

This jewel of a museum holds the biggest collection outside France of the work of sculptor Auguste Rodin (1840–1917). Occupying a 20th-century building designed by French architects Jacques Greber and Paul Cret, it reopened in June 2012 after a brief closing for interior renovations; the idea is to honor Cret's original idea that inside and out offer a "unified setting" for the presentation of sculpture. Entering the museum, you pass through a re-landscaped courtyard to reach Rodin's Gates of Hell—a 21-foot-high sculpture with more than 100 human and animal figures. In the exhibition hall, the sculptor's masterworks are made even more striking by the use of light and shadow. Here are The Kiss, The Burghers of Calais, and Eternal Springtime. A small room is devoted to one of Rodin's most famous sitters, the French novelist Balzac. Photographs by Edward Steichen showing Rodin at work round out the collection.

This replica of a 16th-century guesthouse was reassembled here in 1958 after being exhibited at the Museum of Modern Art in New York City. The architectural setting and the waterfall, gardens, Japanese trees, and pond are a serene contrast with the busy city. The house is called Shofu-So, which means "pine breeze villa," and has a roof made of the bark of the hinoki, a cypress that grows only in the mountains of Japan. There's also 20 murals by acclaimed Japanese contemporary artist Hiroshi Senju here, as well as monthly tea ceremonies, for which reservations are required.

Now Philadelphia's tallest building, the 975-foot Comcast Center is also one of its most eco-friendly: the 58-story design by Robert A.M. Stern Architects uses 40% less water than a traditional office building and also deploys its glass-curtain-wall facade to reduce energy costs significantly. Not to be missed is The Comcast Experience, a 2000-square-foot high-definition video "wall" in the building's "winter garden" lobby, which also features "Humanity in Motion," an installation of 12 life-size figures by Jonathan Borofsky that appear to be striding along girders 110 feet above. The building is also the site of an upscale food court, a steak house, and a seasonal, outdoor café.

Founded more than 175 years ago to honor Benjamin Franklin, this science museum is as clever as its namesake, thanks to an abundance of dazzling hands-on exhibits. To make the best use of your time, study the floor plan before exploring. You can sit in the cockpit of a T-33 jet trainer, trace the route of a corpuscle through the world's largest artificial heart (15,000 times life size), and ride to nowhere on a 350-ton Baldwin steam locomotive. Most visitors flock to a pair of exhibitions: Electricity, which focuses on sustainable energy and includes Franklin's famous lightning rod; and Changing Earth. One don't-miss is the 30-ton white-marble statue of Franklin; you can see the likeness (and an accompanying hourly multimedia presentation) without paying admission.

The Franklin Air Show celebrates powered flight with the Wright Model B Flyer. The Sports Zone conveys the physics, physiology, and material science behind your favorite sport by simulating surfing, testing your center of mass and reaction time, and more. The Fels Planetarium—which has a state-of-the-art aluminum dome, lighting and sound systems, and a related astronomy exhibit, "Space Command"—has shows about the stars, space exploration, comets, and other phenomena. The Tuttleman IMAX Theater, with a 79-foot domed screen and a 56-speaker sound system, screens recent Hollywood films and special documentaries.

There are many great sections of Fairmount Park, but the 1,800 acres around Valley Green known as Wissahickon Park may be the most stunning. Miles and miles of trails running along and above the river lead to covered bridges, a statue of an Indian chief, 17th-century caves of a free-love cult, large boulders that drip water, and ducks. Forbidden Drive, on which cars are forbidden, runs from Northwestern Avenue (the westernmost part of Chestnut Hill) all the way to Lincoln Drive, where it connects to a bike and walking path. This leads eventually to Manayunk and Kelly Drive, where there are additional bike paths that can take you to the city or out along the Schuylkill. Admission to the park is free, but permits are required for bicycles and horses along some trails outside the Forbidden Drive, and a fishing license is required for anglers. There are also many miles of surprisingly difficult mountain-bike trails. The Valley Green Inn is a decent restaurant located on Forbidden Drive and Valley Green Road, and there is a refreshment stand there as well.

The dioramas of animals from around the world displayed in their natural habitats give this natural history museum an old-fashioned charm. The most popular attraction is Dinosaur Hall, with reconstructed skeletons of a Tyrannosaurus rex and some 30 others of its ilk, as well as the "Big Dig," where you can hunt for real fossils, and "Outside-In," an interactive area where kids can crawl through a log, investigate a real beehive, and touch a legless lizard. Another draw is "Butterflies!," where colorful, winged creatures take flight in a tropical garden setting. Founded in 1812, the academy is considered the oldest science-research institution in the western hemisphere and a world leader in the fields of natural-science research, education, and exhibition; the present building dates from 1876. That history is celebrated in the Ewell Sale Stewart Library, a trove natural-history books and artworks.

This high-tech, hands-on science education center is the home of "Shark Realm," a 550,000-gallon tank stretching two stories high and thick with sharks, stingrays, and sawfish. The daring can "swim with the sharks" by snorkeling along the tank's perimeter under the careful supervision of aquarium staff. In the "Hippo Haven" hippopotamuses cohabit with birds, crocodiles, and porcupines. There are also daily "animal experiences," penguin feedings, live animal talks, and "4-D" theater presentations, in which the 3-D on-screen action is choreographed to motion in the theater's seats. To get here, drive or take the ferry from Penn's Landing.

Near the sports complex in deep South Philly, this neoclassical building with big stone arches in FDR Park celebrates Swedish contributions to American history. The Swedes settled the Delaware Valley in the mid-1600s, and it was a pair of Swedish brothers who owned the land William Penn bought and called Philadelphia. This museum is set amid architectural remnants of the nation's 1926 Sesquicentennial Exposition). Modeled after a 17th-century Swedish manor house, it features galleries that concentrate on a certain era or particularly industrious character. The John Ericsson Room honors the designer of the Civil War ironclad ship the Monitor, and the Jenny Lind Room contains memorabilia from the Swedish Nightingale's American tour of 1848–51. One exhibition details Swedish immigration in the 19th century. Other rooms display handmade costumed Swedish peasant dolls, crafts, paintings, and drawings. It's not the most exciting place, but the weird location and building, combined with its examination of forgotten but essential history, make it an interesting visit. You can take the Orange Line subway down Broad Street to Pattison Avenue; when you get out, cross Broad Street and walk five blocks west through the park to the museum.

Penn's official art gallery contains treasures from the university's collections and traveling exhibitions. The gallery shares its historic-landmark building, designed by Frank Furness, with the Fisher Fine Arts Library.

Broad Street, the city's main north–south thoroughfare, has been reinvented as a performing arts district. Although most of the cultural institutions are situated along South Broad Street from City Hall to Spruce Street, the avenue's cultural, education, and arts organizations reach as far south as Washington Avenue in South Philadelphia and as far north as Dauphin Street in North Philadelphia. The main venue is the Kimmel Center for the Performing Arts, at Broad and Spruce streets, which includes a 2,500-seat concert hall designed for the Philadelphia Orchestra. The newest addition is the Suzanne Roberts Theatre, a 365-seat facility that is home to the Philadelphia Theatre Company.

Begun in 1728 by the pioneering botanist John Bartram (1699–1777), this is America's oldest surviving botanical garden. Bartram, with his son William, introduced into cultivation more than 200 native plants from species up and down the East Coast. John became the royal botanist for King George III, and made a fortune selling plants to England. Today the 10-acre historical site along the river has lots of flowering shrubs and trees, including various azaleas, rhododendrons, and magnolias, and the Franklinia, a tree from south Georgia that became extinct in its native habitat and survived only because Bartram gathered it. Although there is almost always something flowering, the best time to come is in May and June, when the gardens are fragrant and filled with the lively chatter of birds. The original 1728 farmhouse still stands, and you can take a tour through its rooms, which have various exhibits, including Native American artifacts from the property dating back 3,000 years. Prince Charles's former gardener David Howard has taken on Bartram's garden as a pet project of sorts. A garden shop is open 10–4 Friday through Sunday. It's tucked down a driveway in an impoverished neighborhood of Southwest Philadelphia; drive or take a cab.

It's easy to find this little brick house with the gabled roof: just look for the 13-star flag displayed from its second-floor window. Whether Betsy Ross, also known as Elizabeth Griscom Ross Ashbourn Claypoole (1752–1836) actually lived here and whether she really made the first Stars and Stripes is debatable. Nonetheless, the house, built around 1740, is a splendid example of a Colonial Philadelphia home and is fun to visit. Owned by the city and maintained by the nonprofit Historic Philadelphia Inc., the eight-room house overflows with artifacts such as a family Bible and Betsy Ross's chest of drawers and reading glasses. The small rooms hold period pieces that reflect the life of this hardworking Quaker (who died at the age of 84, outliving three husbands). You may have to wait in line, as this is one of the city's most popular attractions. The house, with its winding narrow stairs, is not accessible to people with disabilities. Alongside the house is a courtyard with a fountain, as well as the graves of Betsy Ross and her third husband, John Claypoole. Visitors can meet Betsy in her upholstery shop (the only working Colonial upholstery shop in the country) and enjoy free, interactive historical programming in the courtyard from May to September.

Three of the Victorian brownstones on a stretch of 3rd Street near Spruce Street, often called Bouvier's Row, were once owned by the late Jacqueline Kennedy Onassis's ancestors. Michel Bouvier, her great-great-grandfather—the first of the family to come from France—and many of his descendants lie in the family vault at Old St. Mary's Church, a few blocks away on 4th Street.

Located adjacent to the Adventure Aquarium on the Camden waterfront, this delightful 4-acre garden is an interactive horticultural playground with theme exhibits. You can smell, hear, touch, and even taste some of the elements in the Dinosaur, Cityscapes, Picnic, and Storybook exhibits, as well as in the gardens and the Butterfly House. Other attractions include Amaze, Carousel, Train Ride, Tree House, and more. To get here, drive or take the ferry from Penn's Landing.

The basilica of the archdiocese of Philadelphia is the spiritual center for the Philadelphia area's 1.4 million Roman Catholics. Topped by a huge copper dome, it was built between 1846 and 1864 in the Italian Renaissance style. Many of the interior decorations are by Constantino Brumidi, who painted the dome of the U.S. Capitol. Several Philadelphia bishops and archbishops are buried beneath the altar.

Claes Oldenburg's 45-foot-high, 10-ton steel sculpture stands in front of the Center Square Building, above one of the entrances to SEPTA's City Hall subway station. Lauded by some and scorned by others, this pop-art piece contrasts with the traditional statuary so common in Philadelphia.

Graduates of this tuition-free school for outstanding students include Leonard Bernstein, Samuel Barber, Ned Rorem, and Anna Moffo. The school occupies four former private homes; the main building is in the mansion that belonged to banker George W. Childs Drexel. Built in 1893 by the distinguished Boston firm of Peabody and Stearns, it's notable for Romanesque and Renaissance architectural details. Free student and faculty concerts are given from October through May, usually at 8 pm on Monday, Wednesday, and Friday.

Philadelphia's only mid-19th-century house-museum is a Victorian Gothic extravaganza of elongated windows and arches. This gorgeous 1859 suburban villa is used to illustrate the way Victorian social mores were reflected through its decoration. The downstairs highlights the Rococo Revival (circa 1860), the upstairs is fashioned after the Renaissance Revival (1880s), and the difference is striking, especially the Art Deco–like wall details you may not associate with the time. Also striking is the chamber pot in the dining room that the men used after the ladies retired to the parlor. What makes this house particularly interesting is that it was home to middle-upper-class residents, and so much of the decoration represents the norm of what people in that class strove to be. The house is two blocks from the Tulpehocken stop on SEPTA's Chestnut Hill West line.
