Julita Manor and open-air museum is located at the site of former Cistercian Julita abbey. The monastery was originally founded in 1160 at Viby, close to Sigtuna, but under the patronage of King Knut Eriksson, who donated land and a right to parts of the fishing at Älvkarleby, it was moved in 1180 to Säby by the lake Öljaren in Julita. The monastery was therefore also known as Säby, or Saba in Latin. It continued to receive rich donations from King Erik Knutsson (1210-1216), and later from other members of the aristocracy and royal circles. It was finally the owner of some 80 farms, mostly in Södermanland. At the time of the Protestant Reformation, King Gustavus Vasa appropriated the abbey and gave it in fief to Olof Arvidsson, a bailiff in Nyköping, in 1527. The secular estate thus created later had various possessors, including members of the Palbitzki and Lewenhaupt families.
In 1944, the Nordic Museum assumed the ownership of the estate in accordance with the will of the last private owner, Artur Bäckström. The manor is now a large open air museum, incorporating a small part of the abbey in the basement of one of its wings, which is open to the public. Together with another small building originally located outside the cloisters, this is all that can be seen of the abbey today, though archaeological excavations have revealed the full extent of the main abbey buildings.
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.
