The site where Kaggeholm Palace is located was first mentioned in a document in 1287. During the 1500s the farm was owned by members of the families Grip and Bååt. The farm was originally called Vettersjö, but was named by Swedish Count Lars Kagg (1595-1661) who bought the manor during 1647. Kagg was a political ally of King Gustavus Adolphus, a member of the Privy Council of Sweden and Field Marshal during the Thirty Years' War.
The chateau-style mansion was built in 1725 and designed by Nicodemus Tessin the Younger. Since 1939 it has been owned by the Swedish Pentecostal movement and is used as a training center by nearby Kaggeholm College.
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.
