Blaubeuren Abbey was a house of the Benedictine Order founded in 1085 by the Counts of Rück and Tübingen, against the background of the Investiture Controversy and the Hirsau Reforms. The first abbot, Adzelinus, and monks were from Hirsau Abbey. Abbot Fabri was closely involved with the foundation of the University of Tübingen in 1477. In 1493 the high altar was created. The choir stalls by Jörg Syrlin the younger are of a similar date.
The Reformation saw the end of the Roman Catholic monastery, from which the monks were expelled in 1535, returning for a short time between 1549 and 1562. In 1563 the first Protestant abbot was appointed, and in 1565 a choir school was opened in the premises. During the Thirty Years' War the monks returned again in 1630 and yet again in 1648, but were expelled; the choir school closed in 1630 and reopened in 1650. It was finally shut down in 1807.
A few years later in 1817 Blaubeuren became a Protestant seminary with an attached boarding school, which has remained to the present, except for a closure during World War II. The school now operates in co-operation with the similar establishment at Maulbronn Abbey: see Evangelical Seminaries of Maulbronn and Blaubeuren.
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.
