Månstorp was an old manor, Mogenstrup. Its first known owner belonged to the Danish family Hack. Later it was owned by the family Bille, notably Eske Bille who furnished Månstorp with all the luxury of the time. The main building was surrounded by a circular wall and moat. As part of the Scanian compensation estates for the island of Bornholm it passed from the Danish to the Swedish Crown. The castle was given to the Governor General of Scania, Lord High Admiral Gustav Otto Stenbock but later served as the colonel's residence.
During the war from 1675-1679 the castle was occupied by the Swedes and destroyed in 1678. The castle was never reconstructed following its destruction, tumbling down even more to become the ruin it is today.
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.
