Regensburg, a Bavarian city on the Danube River in southeast Germany, is known for its well-preserved medieval core. The 12th-century Stone Bridge, a 310m-long icon with 16 arches, crosses the river to the old town. The 13th-century Regensburg Cathedral, a twin-spired Gothic landmark, is home to the Regensburger Domspatzen choir. Walhalla, a Parthenon replica just east of the city, honors illustrious Germans.
