The first castle at Fosteau was erected in the 14th century. In approximately 1380 Wauthier de Semousies became owner when Duchess Joan of Brabant gave it to him. His successors were the lords of Zwenne, de Marotte, de Henry and de Jamblines. They built several other buildings around the castle. The hall is Gothic.
The castle became a protected monument in 1979. Since 1980, it has housed an exhibition of antique furniture. Everything within the castle is also available for sale.
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.
