Höglwörth Abbey is a former monastery of the Augustinian Canons, dedicated to St. Peter and Paul. It was founded in 1125 by Archbishop Conrad I of Salzburg. It was the only monastery saved from the secularization of Bavaria (1802 and 1803), until Rupertiwinkel became part of the Kingdom of Bavaria in 1816. The last provost Gilbert Grab sought relief from secularization from 1813, but this was not granted until 1816 by the King of Bavaria. On 30 July 1817 it was formally given independence as a privately owned monastery.
The monastery with its rococo church on a peninsula in Lake Höglwörth represents one of the finest ensembles in the eastern Upper Bavaria. The church was rebuilt from 1675. The choir was preserved from the Romanesque church. Before silting to the east the monastery was on an island, but it is now on a peninsula. Wörth is an old word for island, and it is still shown as an island on the field map from the 19th century.
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.
