The ruins of the two castles Rotund and Reichenberg are clearly visible from the village of Taufers in the Münstertal. Rotund Castle is located at an altitude of 1500 metres, making it one of the highest castles in Tyrol. It was built around 900 by order of the bishops of Chur. The castle changed hands several times over the centuries before it was abandoned at the end of the 17th century and left to decay. Below Rotund is Reichenberg Castle. Originally, Reichenberg Castle was owned by the bishops of Chur, but in the middle of the 12th century it fell into the hands of the robber baron, Lord of Reichenberg, who spread fear and terror. At the end of the 17th century, this castle was also abandoned. Today, the ruins of both estates can be visited.
