Heidelberg’s Old Bridge, or Alte Brücke, crosses the Neckar River in nine red sandstone arches, linking the Old Town with the northern bank. Officially named the Karl Theodor Bridge, it was completed in 1788 on a site where earlier crossings had stood since medieval times. The twin-towered Bridge Gate at the Old Town entrance survives from the city’s fortifications.
The bridge has long been one of Heidelberg’s most recognisable sights, appearing in paintings, poems and photographs. Badly damaged during the Second World War, it was rebuilt and reopened in 1947. Today, it is both a route across the river and a place to pause, with views toward Heidelberg Castle, the Old Town rooftops and the wooded hills beyond.
Look for the bronze Bridge Monkey near the Old Town entrance. Local tradition says touching its mirror brings wealth, while touching its fingers promises a return to Heidelberg. For a quieter walk and clearer photographs, come early in the morning; summer afternoons can be busy, especially around the narrow gateway.
The Old Bridge is free to cross and a short walk from Marktplatz via Steingasse. From the northern end, you can continue uphill toward the Philosophenweg for a wider view of the river and castle; wear comfortable shoes, as the climb is steep.
