Hjularöd Castle was first mentioned in 1391, but the current castle was built in 1894-1897. It was built on command of the former owner, chamberlain Hans Gustaf Toll. French medieval castles, the château de Pierrefonds in particular, were inspiration for the castle when architects Isak Gustaf Clason and Lars Israel Wahlman designed it. Outside scenes from the television series Mysteriet på Greveholm (The mystery at Greveholm) in 1996 were filmed in the courtyard of the castle. The castle since 1926 is owned by the Bergengren family and is not open for the public.
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.
