At the confluence of the Hinterrhein and the Vorderrhein, at the birthplace of the Alpine Rhine, is Reichenau. The place was already of great importance in the 14th century, when long-distance traffic over the Graubünden Alpine passes increased and two bridges and a customs house were built. Reichenau is a transport hub, where the routes of the north-south axis separate. Reichenau Castle stands in a spectacular location. Built in the 17th century by the Schauenstein episcopal minister family, it has a long history. The last king of France even lived here once. Today, the historical building belonging to the von Tscharner family is used as a winery.
