The Romantic Road (German: Romantische Straße) is the term for a theme route coined by travel agents in the 1950s to describe the 350 kilometres (220 mi) of highway in southern Germany (in Bavaria and Baden-Württemberg), between Würzburg and Füssen. In medieval times it used to be a trade route, connecting the center of Germany with the South. Today this region is thought by many international travellers to possess "quintessentially" German scenery and culture, specifically in towns and cities such as Nördlingen, Dinkelsbühl and Rothenburg ob der Tauber. The route is also known for passing a lot of castles, such as Burg Harburg and the famous Neuschwanstein Castle. The Romantic Road is marked with brown signs along the road.
