The castle was administered by Loka chiefs, among them Lambergs, Thurms, and Rasps. Since 1890 the castle has been managed by the Ursulines, who pulled down the Romanesque yard tower and transformed it into a school. Since 1959 it has hosted the Loka Museum.
The circular castle dominates above Škofja Loka and presents the conclusion of the town walls. It can be dated after the earthquake in 1511, although some parts are older, which was confirmed during the renovation works in 2006–2008.
