Guardaval Castle

Guardaval Castle is a ruined castle in the municipality of Madulain of the Canton of Graubünden in Switzerland.
Guardaval Castle was built around 1250 near the village of Madulain to administer the estates of the Bishop of Chur in the Upper Engadine by Bishop Volkard von Neuenburg. The castle sat along the Albula Pass road and collected tolls from travelers going over the pass. The castle was an important administrative center for the bishops, they often took up residence in the castle and ordered their vassals to frequently repair and hold it always available to them. Originally the castle consisted of just the main tower. The second building phase added a curtain wall, a gatehouse to the south, a zwinger or outer courtyard and a residential wing to the east.
