In the 12th century on the hills above Škofja Loka stood three fortifications: the Upper Tower on Krancelj, the Lower Fort and the Loka Castle, a residence of Freising Bishops, built at the brink of a natural terrace. The castle is first mentioned in 1202 as castrum firmissimum, although today's building dates from the 16th century. The castle was rebuilt in 1691 after an earthquake and in 1716.
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 town 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. The north-eastern tower, the oldest in the structure, is built on an older predecessor from the 10th century. Together with the renovation work the reconstruction of the primary entrance with a wooden drawbridge was also carried out.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
