Braunau in Rohr Abbey is a monastery of the Augustinian Canons dedicated to the Assumption of the Blessed Virgin Mary. It was founded in 1133 by Adalbert of Rohr. It was dissolved in the secularization of 1803 when the German princes substituted church lands for property they had lost through Napoleon. In the east wing the parish priest's offices and a school were accommodated, and in a part of the west wing, an inn. The remaining buildings were demolished.
The abbey church, dedicated, like the abbey, to the Assumption, contains a high altar, which represents the Assumption of the Virgin in fully three-dimensional sculpture a Theatrum sacrum. It was created by Egid Quirin Asam in 1722 and 1723.
After World War II the exiled German Benedictine monks from Braunau Abbey (Braunau is now Broumov in the Czech Republic) were lodged here in part of the east wing. They gradually re-established their community, acquiring little by little the remaining parts of the entire monastery complex. The monks have re-established a secondary school here.
The abbey has been part of the Bavarian Congregation of the Benedictine Confederation since 1984.
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.
