Wik Castle is one of the best preserved medieval castles in Sweden. The first owner was Israel And in the end of 13th century. The current magnificent castle with seven floors was built in the late 15th century. The massive walls and moats made the stronghold impregnable. During the Middle Ages, the castle was one of the sturdiest strongholds in the Mälaren Valley, and Gustav Wasa once besieged Wik Castle for over a year without ever managing to get inside the walls. It was modified to the present French-style appearance in the 17th century.
Wik Castle has been owned by several noble families like Sparre, Bielke, Horn von Liewe, de Geer and von Essen. Today it is owned by the county council of Uppsala and used primarily for the council's own conference activities. It is at present closed to 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.
