Landgoed Clingendael Manor and Park, Hague

Clingendael is a historic estate located just outside The Hague in Wassenaar, with a 17th-century manor house and surrounding parkland. Since 1982, it has been home to the Netherlands Institute of International Relations Clingendael.

The name Clingendael means "valley in the dunes." In 1591, Philips Doublet acquired the farm and the land around it. The main section of the manor house was constructed between 1643 and 1660 for Philip Doublet III. Several members of the Doublet family served as Treasurer General in the Republic of the Seven United Provinces.

Philip's wife was the sister of the famous poet and statesman, Constantijn Huygens, and Philip's son married one of Huygens' daughters, Suzanna. The original architecture of Clingendael shares some features with Huygens' country house in Voorburg, Hofwijck.

The Japanese Garden at Clingendael was established in the early 20th century by Baroness Marguérite van Brienen, also known as Lady Daisy. Lady Daisy made multiple trips to Japan and brought back various elements, including lanterns, a water cask, sculptures, a pavilion, small bridges, and various plants.

The original design, featuring a serene pond, meandering brook, and winding pathways, has remained unchanged over the years. The Municipality of The Hague has diligently preserved the Japanese Garden due to its uniqueness and historical significance. In 2001, the garden was designated as a national historical monument. Because of its delicate nature, the garden is only open to visitors during a limited period each year.
