The Karl Theodor Bridge, known to everyone as the Old Bridge (Alte Brücke), spans the Neckar between Heidelberg’s Old Town and the Neuenheim district. Completed in 1788 from red Neckar sandstone, it is the city’s defining landmark and the classic place to see Heidelberg Castle rising above the rooftops.
On the Old Town side, you enter through the medieval Bridge Gate, whose twin towers carry white baroque helmets. Beside it sits the bronze Bridge Monkey, a 1979 sculpture by Gernot Rumpf. Visitors rub its fingers for luck and pose with the hollow mirror it holds. Farther along, statues of Elector Karl Theodor and the goddess Minerva watch over the nine arches. Retreating German troops blew up the bridge on 29 March 1945, and residents’ donations funded its faithful reconstruction.
Visitor Highlights & Practical Info
The bridge is open to pedestrians around the clock and free to cross. Tour groups crowd it from late morning through afternoon, especially between May and October and during the Christmas market. Arrive before 9 a.m. for empty arches, or come at dusk, when the castle lights up for photographers. For the best overview, cross to Neuenheim and climb the steep Schlangenweg to the Philosophers’ Walk. The Bismarckplatz tram hub is about 15 minutes on foot along Hauptstrasse, and the Kornmarkt and Heiliggeistkirche lie just behind the gate.
