History+
Hochjuvalt Castle, whose name derives from the Latin “Jugum altum” (high yoke), was probably built in the 12th century as the ancestral seat of the Lords of Juvalt. This family initially served independently and later the Bishop of Chur. A Siegfried von Juvalta was first mentioned in documents around 1140 and 1149 in connection with a legal dispute. In 1342, an inheritance dispute arose between the brothers Albert and Bartholomäus von Juvalt, with Albert being awarded the castle. Later, the castle came into the possession of the Lords of Rietberg. After another inheritance dispute, the Landenberger family relinquished the complex in favor of the bishop. In the 15th century, Hochjuvalt changed hands several times as collateral. Around 1500, the castle was probably abandoned and by 1550 it was already referred to as a ruin.
