14 Best Sights in Regensburg, Franconia and the German Danube

This impressive medieval bridge resting on massive stone pontoons is Regensburg's most celebrated sight. It was completed in 1146 and was rightfully considered a miraculous piece of engineering at the time. As the only crossing point over the Danube for miles, it effectively cemented Regensburg's control over trade. The significance of the little statue on the bridge is a mystery, but the figure seems to be a witness to the legendary rivalry between the master builders of the bridge and those of the Dom.

Erected by the Carolingian order in the 9th century, the Old Chapel's sober exterior hides joyous rococo treasures within—extravagant concoctions of sinuous gilt stucco, rich marble, and giddy frescoes, the whole illuminated by light pouring in from the upper windows.

The picture-book complex of medieval half-timber buildings, with windows large and small and flowers in tubs, is one of the best-preserved town halls in the country, as well as one of the most historically important. It was here, in the imposing Gothic Reichssaal (Imperial Hall), that the Perpetual Imperial Diet met from 1663 to 1806. This parliament of sorts consisted of the emperor, the electors (seven or eight), the princes (about 50), and the burghers, who assembled to discuss and determine the affairs of the far-reaching German lands of the Holy Roman Empire. The hall is sumptuously appointed with tapestries, flags, and heraldic designs. Note the wood ceiling, built in 1408, and the different elevations for the various estates. The Reichssaal is occasionally used for concerts. The neighboring Ratssaal (Council Room) is where the electors met for their consultations. The cellar holds the city's torture chamber; the Fragstatt (Questioning Room); and the execution room, called the Armesünderstübchen (Poor Sinners' Room). Any prisoner who withstood three degrees of questioning without confessing was considered innocent and released—which tells you something about medieval notions of justice.

With its tiny windows, weathered tiles, and pink plaster, this 17th-century tower stands at the south end of the Steinerne Brücke and is one of the most famous symbols of Regensburg. The tower displays a host of items relating to the construction and history of the old bridge. It also offers a gorgeous view of the Regensburg roof landscape. The brooding building with a massive roof to the left of the Brückturm is an old salt warehouse.

Regensburg's transcendent cathedral, modeled on the airy, powerful lines of French Gothic architecture, is something of a rarity this far south in Germany. Begun in the 13th century, it stands on the site of a much earlier Carolingian church. Remarkably, the cathedral can hold 6,000 people, three times the population of Regensburg when building began. Construction dragged on for almost 600 years, until Ludwig I of Bavaria, then ruler of Regensburg, finally had the towers built. These had to be replaced in the mid-1950s. Behind the Dom is a little workshop where a team of 15 stonecutters is busy full-time in summer recutting and restoring parts of the cathedral.

Before heading into the Dom, take time to admire the intricate and frothy carvings of its facade. Inside, the glowing 14th-century stained glass in the choir and the exquisitely detailed statues of the archangel Gabriel and the Virgin in the crossing (the intersection of the nave and the transepts) are among the church's outstanding features.

This museum contains valuable treasures going back to the 11th century. Some of the vestments and the monstrances, which are fine examples of eight centuries' worth of the goldsmith's trade, are still used during special services. The entrance is in the nave.

The municipal museum vividly relates the cultural history of Regensburg. It's one of the highlights of the city, both for its unusual and beautiful setting—a former Gothic monastery—and for its wide-ranging collections, from Roman artifacts to Renaissance tapestries and remains from Regensburg's 16th-century Jewish ghetto. The most significant exhibits are the paintings by Albrecht Altdorfer (1480–1538), a native of Regensburg and, along with Cranach, Grünewald, and Dürer, one of the leading painters of the German Renaissance. Altdorfer's work has the same sense of heightened reality found in that of his contemporaries, in which the lessons of Italian painting are used to produce an emotional rather than a rational effect. His paintings would not have seemed out of place among those of 19th-century Romantics. Far from seeing the world around him as essentially hostile, or at least alien, he saw it as something intrinsically beautiful, whether wild or domesticated. Altdorfer made two drawings of the old synagogue of Regensburg, priceless documents that are on exhibit here.

This lovely church, in the baroque style from crypt to cupola, stands next to the Alte Kapelle. It has a finely decorated facade designed by the 17th-century Italian master Carlo Lurago.

Prior to 1519, this oversized square was once the heart of the Jewish ghetto. The Neupfarrkirche (New Parish Church) here, built as a pilgrimage church, was given to the Protestants, hence its bare-bones interior. In the late 1990s, excavation work on the square uncovered well-kept cellars and, to the west of the church, the old synagogue, including the foundations of its Romanesque predecessor. Archaeologists salvaged the few items they could from the old stones. Recovered items were carefully restored and are on exhibit in the Historisches Museum. Only one small underground area to the south of the church, the Document, accommodates viewing of the foundations. In a former cellar, surrounded by the original walls, visitors can watch a short video reconstructing life in the old Jewish ghetto. Over the old synagogue, the Israeli artist Dani Karavan designed a stylized plaza where people can sit and meet.

In AD 179 the Romans built a rough-hewn stone gate in the northern wall of the Roman military camp. The Porta Praetoria  is one of the most interesting relics of Castra Regina. Look through the grille on its east side to see a section of the original Roman road, about 10 feet below today's street level.

Formerly a Benedictine monastery, this is the ancestral home of the princely Thurn und Taxis family, which made its fame and fortune after being granted the right to carry official and private mail throughout the empire ruled by Emperor Maximilian I (1493–1519) and by Philip I, King of Spain. Their horn still symbolizes the post office in several European countries. After the death of her husband, Prince Johannes, in 1990, the young dowager Princess Gloria von Thurn und Taxis put many of the palace's treasures on display. A visit to the State Rooms include the splendid ballroom and throne room, allowing you to witness the setting of courtly life in the 19th century (guided tours only). A visit usually includes the fine Kreuzgang (cloister) of the former abbey. The items in the Princely Treasury have been carefully selected for their fine craftsmanship—be it dueling pistols, a plain marshal's staff, a boudoir, or a snuffbox. The palace's Marstallmuseum (former royal stables) holds the family's coaches and carriages as well as related items.

The family church of the Thurn und Taxis family stands across from their ancestral palace, the Schloss Emmeram. The foundations of the church date to the 7th and 8th centuries. A richly decorated baroque interior was added in 1730 by the Asam brothers. St. Emmeram contains the graves of the 7th-century martyred Regensburg bishop Emmeram and the 10th-century saint Wolfgang.

This is a sight you won't want to miss if you have an interest in the wilder expressions of newfound 19th-century pan-Germanic nationalism. Walhalla—a name resonant with Nordic mythology—was where the god Odin received the souls of dead heroes. Ludwig I erected this monumental pantheon temple in 1840 to honor important Germans from ages past, kept current with busts of Albert Einstein and Sophie Scholl. In keeping with the neoclassical style of the time, it is actually a copy of the Parthenon in Athens. The expanses of costly marble are evidence of both the financial resources and the craftsmanship at Ludwig's command. Walhalla may be kitschy, but the fantastic view it affords over the Danube and the wide countryside is definitely worth a look. A boat ride from the Steinerne Brücke in Regensburg is the best way to go. To get to the temple from the river, you'll have to climb 358 marble steps.

Roughly 25 km (15 miles) southwest of Regensburg you'll find the great Weltenburg Benedictine Abbey sitting serenely on the bank of the Danube River. The most dramatic approach to the abbey is by boat (€10.50 round-trip) from Kelheim, 10 km (6 miles) downstream. On the stunning ride the boat winds between towering limestone cliffs that rise straight up from the tree-lined riverbanks. The abbey, constructed between 1716 and 1718, is commonly regarded as the masterpiece of the brothers Cosmas Damian and Egid Quirin Asam, two leading baroque architects and decorators of Bavaria. Their extraordinary composition of painted figures whirling on the ceiling, lavish and brilliantly polished marble, highly wrought statuary, and stucco figures dancing in rhythmic arabesques across the curving walls is the epitome of Bavarian baroque. Note especially the bronze equestrian statue of St. George above the high altar, reaching down imperiously with his flamelike, twisted gilt sword to dispatch the winged dragon at his feet. In Kelheim there are two boat companies that offer trips to Kloster Weltenburg every 30 minutes in summer. You cannot miss the landing stages and the huge parking lot. No Bavarian monastery is complete without a brewery and Kloster Weltenburg's is well worth visiting.
