The cathedral that gives the upper town its skyline — four octagonal towers over a powerful Romanesque-Gothic nave, consecrated in 1237 after a fire destroyed the earlier building. Inside is one of the great gatherings of medieval sculpture in Germany: the Bamberg Horseman in the north aisle, the tomb of emperor Henry II and his wife Kunigunde by Tilman Riemenschneider, and a marble papal tomb — Pope Clement II is the only pope buried north of the Alps.
Free to enter; the cathedral square outside, framed by the Alte Hofhaltung and the Neue Residenz, is the most photographed space in the city.
