Bogenšperk Castle is a 16th-century castle. It is best known for its association with the 17th-century historian Johann Weikhard von Valvasor. Standing on a low hill, the Renaissance castle is fully restored, and is listed as an important cultural monument of Slovenia. The three-story building consists of four tracts from several time periods, connecting four towers and surrounding an arcaded inner courtyard. The oldest part of the castle is the north tower, which originally stood as a standalone fortification. A wooden bridge was later added, linking it to the south-east tower, which originally served a defensive purpose and was once much higher than the rest of the building; however, since a 1759 fire caused by a lightning-strike heavily damaged the castle, the tower was never rebuilt to its original level. The castle stands on bedrock; one of its attractions is a deep well carved directly into the rock.
In its current form, the castle was likely begun by the noble house of Wagen as a replacement for Boltežar Wagen's nearby Castle Lihtenberk, already in disrepair and severely damaged by a major earthquake in 1511. After the 1630 death of Jurij Wagen, the last member of the family, the castle changed several owners until it was in 1672 finally bought by Johann Weikhard von Valvasor after his return from abroad. Thoroughly renovated, it was furnished with a graphic studio, a library, printing press and collection of curiosities. Due to the enormous cost of issuing Valvasor's book, The Glory of the Duchy of Carniola, Valvasor became heavily indebted, and was forced to sell first his valuable library and, in 1692, his estates. His family moved to Krško, while the castle again changed several owners, the last being the noble family Windischgrätz, who abandoned the castle in 1943. While its interior furnishings were destroyed or looted, the castle itself survived the war intact and was in its immediate aftermath turned into a military hospital. From 1957 it was occupied by Jesuits, who carried out some preventive maintenance on the structure; in 1972, a systematic reconstruction effort began, at first led by the art historian Milan Železnik.
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.
