Heemstede castle was first built in 1280 by Dirk van Hoylede from the region of Vlaardingen. Built, burned and rebuilt over the centuries, it was last torn down in 1810, after years of neglect. The monumental gatekeeper's house 'Nederhuys', built in 1630 remains intact as well as the foundations from the Middle Ages. The most famous owner of the castle was Adriaan Pauw, who bought it in 1620. He played a role in the Treaty of Munster, and built the bridge Pons Pacis to commemorate the peace treaty.
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.
