After being privately owned for centuries, Baron van Zuylen van Nijevelt van de Haar placed the castle and surrounding gardens (approximately 55 acres) into the Kasteel de Haar Foundation in 2000 to carry out the necessary restoration and preserve the castle for the future.

Also in the year 2000, the Haarzuilens estate (the 400 acres outside the castle and gardens) was purchased by the Vereniging Natuurmonumenten. In this transaction, Natuurmonumenten gave 20 million euros to Stichting Kasteel de Haar, this money was used for the restoration of castle and gardens.

Owner
On January 2, 2011, Baron Thierry van Zuylen van Nijevelt van de Haar, the last resident of the castle, passed away at the age of 78. The family traditions will be continued by the baron's five daughters. Although they do not own the castle, they do retain the right to stay at the castle during the month of September.

Objective of the foundation
Kasteel de Haar Foundation aims to preserve the unity of the estate and the castle and to ensure that the castle can remain open to the public now and in the future so that visitors can enjoy the unique ensemble of castle, interior and surroundings.

Activities
To keep the castle in good condition a lot of maintenance is needed. Stichting Kasteel de Haar tries to earn the annual funds needed for this itself and does not receive any subsidy for the museum task. To still obtain the necessary funds, the foundation organizes many activities each year in the field of tourism, business and private receptions and events.

By visiting the gardens, the castle and one of our events, by having your wedding blessed here, celebrating your company party and by making a purchase in our castle store, you are contributing to the preservation of the castle, collection and gardens.

Volunteers
Stichting Kasteel de Haar would not be able to accomplish all of this without the efforts of over 230 volunteers who lovingly dedicate themselves to the preservation of De Haar. Because of this, Stichting Kasteel de Haar is able to let visitors enjoy all the beauty that De Haar has to offer.
