The first known owner of Ovesholm estate was Åke Holm in 1580. In 1620 Ove Urup built an earlier main building near to the current site. In 1774 it was donated to Henning Reinhold Wrangel and his son Carl Adam Wrangel af Adinal built the present castle between 1792-1804. Carl Adam also created a notable library and collection of art and sculptures to Ovesholm. The latest enlargement was made by Axel Hugo Raoul Hamilton in 1857. Today Ovesholm is still in Hamilton family's possession and not open 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.
