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:
Goryōkaku (五稜郭) (literally, 'five-point fort') is a star fort in the Japanese city of Hakodate on the island of Hokkaido. The fortress was completed in 1866. It was the main fortress of the short-lived Republic of Ezo.
Goryōkaku was designed in 1855 by Takeda Ayasaburō and Jules Brunet. Their plans was based on the work of the French architect Vauban. The fortress was completed in 1866, two years before the collapse of the Tokugawa Shogunate. It is shaped like a five-pointed star. This allowed for greater numbers of gun emplacements on its walls than a traditional Japanese fortress, and reduced the number of blind spots where a cannon could not fire.
The fort was built by the Tokugawa shogunate to protect the Tsugaru Strait against a possible invasion by the Meiji government.
Goryōkaku is famous as the site of the last battle of the Boshin War.
