Bergen auf Rügen Abbey was a monastery for Cistercian nuns. It lasted from the end of the 12th century to the early 16th century as a Roman-Catholic monastery and then, until 1945, as an Evangelical aristocratic nunnery.
The Principality of Rügen belonged to the Bishopric of Roskilde since its conquest by the Danes in 1168, Bishop Absalon of Lund being responsible for introducing the territory to Christianity. In 1193, Prince Jaromar I of Rügen founded a nunnery near the fort (Burgwall) on the Rugard, and had it consecrated as St. Mary's Church which had originally been planned as a palace church (Pfalzkirche). The monastery was a branch of St. Mary's Abbey, Roskilde, from which the first Benedictine sisters came. When the two monasteries transferred to the Cistercian order is not known. A confirmation of the Cistercian ordinances and possessions was made by Pope Innocent IV in 1250.
On its foundation, Jaromar I granted the monastery with extensive, but scattered, estates, which were mostly on the island of Rügen. Until the mid-14th century are only a few donations by his followers or internal documents of the monastery known. After that it was increasingly involved in the purchase of whole parishes, such as in 1344, which consisted of 14 villages, and in 1357 the estates of Arnold Pape, the goods of John of Kiel in Wieck, Dranske and Goos.
References:The Citadelle of Quebec is an active military installation and official residence of both the Canadian monarch and the Governor General of Canada. It is located atop Cap Diamant, adjoining the Plains of Abraham in Quebec City. The citadel is the oldest military building in Canada, and forms part of the fortifications of Quebec City, which is one of only two cities in North America still surrounded by fortifications, the other being Campeche, Mexico.
The first fortifications in Quebec were built by the Governor General of New France Louis de Buade, and completed just in time for the Battle of Quebec in 1690.
After the British conquest in the second half of the 18th century, the problem of Quebec City's defences grew more acute.
