Moorsel was owned by the chapter of Dendermonde, probably from 868 on. One of the largest landowners in the region was the Abbey of Affligem, who possessed the church and the parish of Moorsel. Abbot Karl de Croy, Bishop of Tournai, built a water castle at Moorsel in 1546. The renaissance castle is still preserved in its original condition. The castle is constructed was intended as a summer residence for the Karl de Croy.
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.
