Bladenhorst castle was first mentioed in 1266 as the residence of the lords of Blarnhurst lived there. At the beginning of the 14th century it became the possession of the family of Düngelen. In 1338, Rötger Düngelen made the castle available to the Duchy of Cleves to use in the event of war. Through marriage, in 1496 the castle passed to Philip of Viermünden. From 1624 to 1881 it was inherited by the Westphalian noble family of von Romberg.
The structure originally consisted of four wings. The gatehouse is the oldest part of the building, the chapel dates from 1332. The castle as it stands is in the style of the Renaissance - coming from its rebuilding between 1530 and 1584.
Today castle is still inhabited, and privately owned, consequently there are no public tours or visits, some parts of the castle are rented out to private individuals.
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.
