Schlehdorf Abbey was originally a Benedictine monastery, later an Augustinian monastery, and is today a convent of the Missionary Dominican Sisters of King William's Town.
The abbey, dedicated to Saints Dionysius and Tertullinus, was founded around perhaps 740 from the nearby Benediktbeuern Abbey. In 769 it was resettled by monks from the abandoned Scharnitz Abbey. The first abbot, Atto, brought with him the relics of Saint Tertullinus. It was a Benedictine monastery until the 9th century, after which it is heard of no more; presumably it was destroyed during the Hungarian invasions. From 1140 it was revived as a house of the Augustinian Canons.
In 1803 it was dissolved during the secularisation of Bavaria, and sold off. Since 1904 Schlehdorf has belonged to the Missionary Dominican Sisters of King William's Town. It has been the seat of the German Province of the Order since 1960, and as of 2010 is a community of about 60 Dominican sisters. In the abbey grounds, besides a guesthouse and the abbey shop, is a girls' secondary school of the diocese of Munich and Freising.
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.
