The Regensburg Museum of History, currently resides in a former Minorite monastery, is a museum of the history, art and culture of Regensburg and eastern Bavaria from the Stone Age to the present day.
The former monastery of St Salvator, located in the city's Dachauplatz district, was founded in 1221 by the Bishop of Regensburg Konrad IV of Frontenhausen, Count Otto VIII of Bavaria, and King Henry VII. The three-naved basilica church was considered the largest church of the order in southern Germany until its closure in 1799.
The church and most of its monastic buildings survived, with the monastic buildings converted as barracks and billets for the Bavarian Army, and the church as a customs hall, a drill hall and a hotel until it became the location of the Regensburg Museum of History in 1931.
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.
