St. Stephen's Abbey, dedicated to Saint Stephen, was founded in 969 by Saint Ulrich, Bishop of Augsburg, and used by Augustinian canonesses. It was dissolved in the secularisation of Bavaria in 1803, and the premises passed into the possession of the town. The army used the site for a few years as a quartermaster's store.
In 1828 King Ludwig I of Bavaria founded a grammar school here, as a successor to the former Jesuit college of St. Salvator (1582–1807). In 1835 he established the Benedictine monastery and entrusted it with the running of the school. The buildings were entirely destroyed in 1944 but have been re-built.
The monks continue to run the school and boarding house, and are engaged in pastoral and youth work.
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.
