Maassluis (Dutch pronunciation:[maˑˈslʌy̆s]ⓘ) is a town in the westernNetherlands, in the province ofSouth Holland. The municipality had a population of 33,567 in 2021 and covered 10.12 km2 (3.91 sq mi) of which 1.64 km2 (0.63 sq mi) was water.
Maassluis was founded circa 1340 as a settlement next to alock (in Dutch:sluis) in the sea barrier between theNorth Sea andRotterdam. OriginallyMaeslandsluys, it was part ofMaesland. In 1489 the settlement was sacked. During theEighty Years' War,Philips of Marnix, lord of Sint-Aldegonde, started to build a defense wall but before its completion, the Spanish captured it in 1573[5] and Philips of Marnix was taken prisoner. A year later Maeslandsluys was looted bymutinous Spanish troops.
On 16 May 1614, Maeslandsluys was separated from Maesland by the counts of Holland and renamed Maassluis. This separation may have been religiously motivated: Maassluis was predominantly Protestant andMaasland Catholic. In 1624 the defense wall was demolished to make way for the Great Church, started in 1629. Construction stopped for five years because privateers from Dunkirk raided fishing boats from Maassluis, throwing their crew overboard. It was finished in 1639. On 4 December 1732, the Garrels Organ was inaugurated. Built from 1730 to 1732 by Rudolf Garrels, a pupil ofArp Schnitger, it was a gift by Govert van Wijn, ship-owner from Maassluis.[6]
The Jewish community had its own synagogue, a teacher, a singer and a ritual butcher. Its most common professions were salesman, street trader and butcher. The economy was vulnerable and community growth ended with the industrial revolution. The area became easier to reach and competition became too much. The number of Jews fell from 92 to eight between 1892 and 1930. A cause was the building of a railway in 1881 between Maassluis and Rotterdam. Most Jewish traders moved to Rotterdam, The Hague and Amsterdam, which in the last decade of the 19th century had a growing Jewish population.
Integration in Maassluis ended during the Second World War. The Coltof and Van Gelderen families were deported in 1942 and murdered in Auschwitz.
Maassluis was historically dependent on the fishing near the coast and off Iceland. In the 19th century the tugboat company, L. Smit, and themarine salvage company W.A. van den Tak merged to become Smit-Tak, now a division of the world's largest salvage company,Smit International. Also, there is still a large shipping agency called Royal Dirkzwager. Maassluis is now mainly a commuter town forRotterdam.
