Stolpe Abbey was the first monastery in Pomerania. Ratibor I, Duke of Pomerania, founded the abbey on 3 May 1153 in memory of his brother Wartislaw I. Wartislaw, who had subdued the area and converted its people to Christianity in the late 1120s, was killed near the site of the future monastery; according to legend he was murdered by a Liutician pagan.
The abbey was settled by Benedictine monks from Berge Abbey near Magdeburg. The Pomeranian dukes and the Counts of Gützkow granted the new foundation extensive lands in the vicinity. In 1164, a meeting between the Duke of Saxony, Henry the Lion, and King Valdemar I of Denmark was held here.
In 1304, the abbey became part of the Cistercian Order, and was made a daughter house of Pforta Abbey. In 1305, Kärkna Abbey (also known as Falkenau Abbey) and in 1319 Padise Abbey, both in Estonia, were put under the authority of Stolpe.
In 1534, Stolpe Abbey was dissolved in the course of the Protestant Reformation. The Thirty Years' War made a battleground of Stolpe and left the abbey buildings in ruins.
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.
