During the Bündner Wirren, in May 1662, the castle was occupied by 200 men under the command of a Colonel Baldrion.

The castle is built on the top of a narrow hill near Haldenstein with steep cliffs on two sides.

A three-story living quarters building was built on the highest point of the hilltop.
