Routes and places linked to the The Romantic Road or Romantische Straße. It is a "theme route" devised by promotion-minded travel agents in the 1950s. It describes the 350 kilometres (220 mi) of surface roads between Würzburg and Füssen in southern Germany, specifically in Bavaria and Baden-Württemberg, linking a number of picturesque towns and castles. In medieval times, it was a trade route that connected the center of Germany with the south. Today, this region is thought by many international travellers to possess "quintessentially German" scenery and culture, in towns and cities such as Nördlingen, Dinkelsbühl and Rothenburg ob der Tauber and in castles such as Burg Harburg and the famous Neuschwanstein. The Romantic Road is marked along the way with brown signs.
