Philips van Wassenaar (died in 1225) is considered to have been the founder of Nederhorst Castle. In the 17th century the baron Godard van Reede had the Reevaart dug so that his visitors could disembark in front of the castle when arriving by boat. The castle was thoroughly rennovated in the 18th century, and reminders of this period can still be seen on the south side.
After 1945 the castle fell into a serious state of disrepair and there was even question of it being pulled down. However the building found a saviour at the end of 1959 in the form of a moped manufacturer from Bussum who had heard from his general practitioner that there was a castle for sale in Nederhorst den Berg. This artisan, Jan Lourens Jonker, married to Harmine J.E. Wolters, was looking for space for his hobbies: collecting old bicycles and clocks.
After a disastrous fire in 1971, and with the help of additional funding by state, provincial and local governments, renovation could begin. Restoration was completed in 1973. Today the castle hosts a private company Studio Michel Mulders.
References:The Broch of Gurness is an Iron Age broch village. Settlement here began sometime between 500 and 200 BC. At the centre of the settlement is a stone tower or broch, which once probably reached a height of around 10 metres. Its interior is divided into sections by upright slabs. The tower features two skins of drystone walls, with stone-floored galleries in between. These are accessed by steps. Stone ledges suggest that there was once an upper storey with a timber floor. The roof would have been thatched, surrounded by a wall walk linked by stairs to the ground floor. The broch features two hearths and a subterranean stone cistern with steps leading down into it. It is thought to have some religious significance, relating to an Iron Age cult of the underground.
The remains of the central tower are up to 3.6 metres high, and the stone walls are up to 4.1 metres thick.
