A stone house on the site of current Mheer Castle was first mentioned in 1314. It was probably built long before that, because the Lords of Mheer were already mentioned around 1100. In the 14th century the castle went to the Van Imstenraedt family through marriage. The castle stayed in this family until 1668, then it went to the De Loƫ family. They still own the castle.
The castle is situated against the slope of a hill and thus has a dry moat. From the original 14th century castle only wall fragments remain. This original castle probably consisted of three wings surrounding a courtyard with the fourth side closed by a curtain wall. The present bailey dates back to the 16th and 17th century.
The present castle was rebuilt, with the use of original wall fragments, on the medieval foundations in the 17th century. Also in later centuries, up until the 20th century, a lot of rebuilding took place.
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.
