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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
