Map - Wassenaar (Gemeente Wassenaar)

Wassenaar (population: 0 in ) is a municipality and town located in the province of South Holland, on the western coast of the Netherlands.

An affluent suburb of The Hague, Wassenaar lies 10 km north of that city on the N44/A44 highway near the North Sea coast. It is part of the Haaglanden region and the Rotterdam–The Hague metropolitan area. The municipality covers an area of undefined km2, of which undefined km2 is covered by water.

Wassenaar is home to some of the Netherlands' richest residential neighborhoods as well as the country's most expensive street, the Groot Haesebroekseweg.

There are rumours that the 12th-century Romanesque church in Wassenaar lies on the spot where the Northumbrian missionary Willibrord once landed in the Netherlands; the high dunes to the west were not formed until later.

Wassenaar long remained an unremarkable little town, known only as the home of the House of Wassenaer. It only began to gain notoriety in the 19th century when Louis Bonaparte ordered the construction of the Heerweg ("Army Road") between The Hague and Leiden, which forms the current Rijksstraatweg. In approximately 1840, Prince Frederik had the De Paauw (Peacock) palace built, where he lived for many years; it now serves as the city hall of Wassenaar.

The construction of the railway connected Rotterdam, The Hague, through Wassenaar towards its final destination the coastal area of Scheveningen in 1907, the course of which now forms the Landscheidingsweg. Wassenaar became attractive as a residence for wealthy people from Rotterdam. Buildings such as the monumental Huize Ivicke were constructed.

From September 1944 to March 1945 Wassenaar was one of launching sites used by the German Luftwaffe, commanded by SS General Hans Kammler for the V-2 rockets directed mainly towards London.

On one of the main routes to the Wassenaarseslag, the main beach for Wassenaarders, a World War II bunker can be found. For safety reasons and the instability of the structure, it was sealed off to prevent entrance.

The American World War II and Korean War general Haywood Hansell, who helped plan the Allied bombing offensive against both Germany and Japan, lived in Wassenaar in retirement from 1957 to 1966.

In 1982 the Wassenaar Agreement between employers' organisations and trade unions in the Netherlands was signed here. This groundbreaking agreement helped in restraining wage growth in return for the adoption of policies to combat unemployment and inflation.
