5 Best Sights in Barcelona, Spain

This fascinating museum just off Plaça del Rei traces Barcelona's evolution from its first Iberian settlement through its Roman and Visigothic ages and beyond. The Romans took the city during the Punic Wars, and you can tour underground remains of their Colonia Favencia Iulia Augusta Paterna Barcino (Favored Colony of the Father Julius Augustus Barcino) via metal walkways. Some 43,000 square feet of archaeological artifacts, from the walls of houses, to mosaics and fluted columns, workshops (for pressing olive oil and salted fish paste), and street systems, can be found in large part beneath the plaça. See how the Visigoths and their descendants built the early medieval walls on top of these ruins, recycling chunks of Roman stone and concrete, bits of columns, and even headstones. In the ground-floor gallery is a striking collection of marble busts and funerary urns discovered in the course of the excavations. Guided tours are available in English at 10:30 am daily, but have to be reserved in advance. The price of admission to the museum includes entry to the other treasures of the Plaça del Rei, including the Palau Reial Major, the splendid Saló del Tinell, and the chapel of Santa Àgata. Also included are visits to other sites maintained by the museum: the most important and central of these are the Temple of Augustus, the Door of the Sea (the largest of the Roman-era city gates) and Dockside Thermal Baths, the Roman Funeral Way in the Plaça de la Vila de Madrid, and the Call (medieval Barcelona's Jewish quarter).

This superb museum is housed in the 13th-century Drassanes Reials (Royal Shipyards), at the foot of La Rambla adjacent to the harborfront. This vast covered complex launched the ships of Catalonia's powerful Mediterranean fleet directly from its yards into the port (the water once reached the level of the eastern facade of the building). Today, these are the world's largest and best-preserved medieval shipyards. Centuries ago, at a time when the region around Athens was a province of the House of Aragón (1311–90), they were of crucial importance to the sea power of Catalonia (then the heavyweight in an alliance with Aragón).

On the Avinguda del Paral·lel side of Drassanes is a completely intact section of the 14th- to 15th-century walls—Barcelona's third and final ramparts—that encircled El Raval along the Paral·lel and the Rondas de Sant Pau, Sant Antoni, and Universitat. (Ronda, the term used for the "rounds," or patrols soldiers made atop the defensive walls, became the name for the avenues that replaced them.)

The Museu Marítim is filled with vessels, including a spectacular collection of ship models. The life-size reconstruction of the galley of Juan de Austria, commander of the Spanish fleet in the Battle of Lepanto, is perhaps the most impressive display in the museum. Figureheads, nautical gear, early navigational charts, and medieval nautical lore enhance the experience, and headphones and infrared pointers provide a first-rate self-guided tour.

Concerts are occasionally held in this acoustic gem. The cafeteria-restaurant Norai, open daily 9 am to 8 pm, offers dining in a setting of medieval elegance, and has a charming terrace. Admission to the museum includes a visit to the schooner Santa Eulàlia, a meticulously restored clipper built in 1918, which is moored nearby at the Port Vell.

Just downhill to the right of the Palau Nacional, the Museum of Archaeology holds important finds from the Greek ruins at Empúries, on the Costa Brava. These are shown alongside fascinating objects from, and explanations of, megalithic Spain.

Established in what used to be a port warehouse, this state-of-the-art interactive museum makes you part of Catalonian history, from prehistoric times to the contemporary democratic era. After centuries of "official" Catalan history dictated from Madrid (from 1714 until the mid-19th century Renaixença, and from 1939 to 1975), this offers an opportunity to revisit Catalonia's autobiography. Audioguides are available in English. The rooftop restaurant (1881 Per Sagardi) has fabulous harbor views.

Presumably you came to Barcelona to learn about Catalonia, not ancient Egypt, but you might be making a mistake by skipping this major collection of art and artifacts. This museum takes advantage of state-of-the-art curatorial techniques, with exhibitions showcasing everything from mummies to what the ancient Egyptians had for dinner. The museum offers free guided tours, but only in Catalan or Spanish.
