Prüll Charterhouse is a former Carthusian monastery. The monastery, dedicated to Saint Vitus, was established as Prüll Abbey, a Benedictine foundation, in 997 by Gebhard I, Bishop of Regensburg, and his brother Rapoto. In about 1100 the Ottonian church building was replaced by a Romanesque hall church, the first of the sort in Bavaria.
In 1484 Prüll became a Carthusian monastery, with the support of Albert IV, Duke of Bavaria, and later his son William IV. Substantial additions were made to the buildings to adapt them for Carthusian use. In the church additional choirs were built, stained glass from which is now in the Bayerisches Nationalmuseum in Munich.
It was dissolved in 1803 in the secularisation of Bavaria.
The monastery church fell into decay. Half of the monks' cells, the chapter room, the refectory and the library were demolished. What remained of the premises was acquired in 1835 by the Bavarian state. In 1852 a lunatic asylum was accommodated here. Today the buildings are the home of the Regensburg District Clinic.
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.
