Heidelberg’s Altstadt has a red-roofed townscape of remarkable architectural unity. After having been all but destroyed by French troops under Louis XIV (1690s), it was built pretty much from scratch during the 18th century. Unlike the vast majority of German cities, it emerged from WWII almost unscathed. Today, Heidelberg is one of Germany’s most romantic cities – and the romance builds the longer you stay: the more you wander around, the more unexpected beauty and heartstopping panoramas you’ll discover.
