Noordwijk (pronounced [ˈnoːrtʋɛik] ⓘ) is a town and municipality in the west of the Netherlands, in the province of South Holland.

Until the beginning of the 19th century, fishing remained its primary business, but then began to be replaced by the growing tourism industry.

Nowadays because of its long sandy beaches, it is a popular resort town with 1,000,000 overnight stays per year.

North (and to a lesser extent south) of Noordwijk spreads a relatively vast dune area, in which a varied wild flora and fauna (with among others pine forests and deer) is observable for bikers, walkers and gallopers.

Public figures who lived in Noordwijk or sought recovery were Thomas Mann, Maria Montessori (buried in Noordwijk) among others, the entrepreneur Alfred Heineken, ex-Empress Soraya,[5] the poet Henriette Roland Holst, the psychoanalyst Sigmund Freud, the writer Stefan George, the pianist Pia Beck, the tenor Jacques Urlus, the writer Margriet de Moor as well as painters and artists such as Marinus Gidding, Gerard van der Laan, Max Liebermann,[6] Daniël Noteboom, Jan Hillebrand Wijsmuller[7] and known film actors.

In March 2014, the US President Barack Obama and General Secretary of the Chinese Communist Party Xi Jinping stayed in Noordwijk[8] Part of Martin Ritt's adaptation of John le Carre's The Spy Who Came in from the Cold (1965), starring Richard Burton, was filmed at Koningin Astrid Boulevard in Noordwijk.

Some 80 bunkers and underground structures housed 180 soldiers, and were connected by 400 metres (a quarter-mile) of tunnels, equipped with narrow rail-tracks for moving heavy ammunition.

The central, S414 design, fire command bunker alone counts three-man-high stories deep, and with walls up to 3 metres (10 feet) thick, it consists of more than 1,800 m3 of concrete – the equivalent content of some 300 modern cement trucks.
