The Abbey of the Holy Cross in Rostock was founded in the 13th century by Cistercian nuns. It is the only completely preserved abbey in the city. The complex includes the former abbey church which is used today as the University Church (Universitätskirche). The remaining convent buildings house the Museum of Cultural History (Kulturhistorische Museum) for the city of Rostock.
The nunnery was founded by the Danish Queen Margaret in 1270. According to legend, she founded the nunnery in gratitude for a miraculous rescue at sea in the vicinity of Hundsburg castle at Schmarl. What is certain is that she made large donations to the nunnery. She died in 1282 and was buried in the minster church in Bad Doberan which belonged to the Cistercian Order. The nunnery gained extensive estates in Rostock and also in the whole of Mecklenburg as a result of donations, endowments and bequests. The nuns came mostly from wealthy families in Rostock. The nunnery was very popular and even had to place restrictions on entry in the 14th century. The abbey church was completed in 1360.
The Reformation was accepted into the abbey in 1562 after just thirty years of 'contemplation time' by the nuns in the convent. As a result of the Second Rostock Inheritance Agreement between the city of Rostock and the dukes of Mecklenburg in 1584 the nunnery was turned into a Lutheran damsels' convent (Frauenstift). The lives of its conventuals, however, hardly changed at all. The place still resembled a Roman Catholic monastic order. After the Thirty Years' War, however, there were only nine conventuals. In the 19th century, efforts were made to transfer the estate of the nunnery to the state. But it was not until 1920, when the Free State of Mecklenburg-Schwerin constitution was introduced, that the state appropriated all such parastatal entities, such as women's convents. As a result, Mecklenburg-Schwerin's Lutheran church was only allowed to continue legally as an organisation independent of the state. The effect of this was that the nunnery was expropriated by the state without any compensation to the church. On 17 August 1920, the abbey was dissolved, although the remaining conventuals were allowed the right to live there for life. The last abbess died in 1981. The abbey church was renovated both outside and, later, inside from 1997 to 2002. The convent buildings now house the Rostock Museum of Cultural History.
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.
