Rhoon Castle as we know today was built in 1430 by Pieter the Seventh of Duiveland. He was a descendant of Biggo van Duiveland, who built the original castle which dated back to 1199. The coats of arms of the many illustrious families who lived in the castle can be seen in the stained-glass windows in the Catharina Theresia Room. Thoroughly restored in 1975, the castle is now regarded as one of the most beautiful restaurants in the Netherlands.
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.
