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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
