The castle was mentioned for the first time in 1215 and took a more significant role after 1511, when the earthquake broke down the Upper tower on Krancelj (the latter was until then the seat of the Loka lordship). The settlement itself under the Loka Castle began to emerge as early as the 13th century, mostly inhabited by traders and craftsmen. The Loška Castle was nationalized in 1803, at that time it was also the official end of the Loka lordship. The state arranged various offices in the premises of the castle, from the tax office, the court to the land register. In 1870, the castle was purchased by Fidelis Terpinc, and five years later Emilia Baumgartner became the owner. In 1890, the castle went into possession of Ursulines, which bought it from Emilia Baumgartner's daughter for a price of 10,000 crons. Ursulines started the renovation of the castle, the work was entrusted to the architect Viljem Treu. He gave the connection with the monastery in the center of the castle, also demolished the middle tower, built a narrower and higher belfry. In 1893, the renovated building was blessed by kardinal Jakob Missia. During the First World War, a military hospital was in the castle. During the two wars, Ursulines continued their educational and school work. In 1941 their activities were barred when the Germans occupied the castle. Immediately after the war, there was a filtration and penitentiary camp. In 1959 the castle was taken over by the municipality. At that time, the Loški muzej started working in it, and the castle was dedicated to museum activities.
