Hellevoetsluis
Hellevoetsluis () is a small city in the western Netherlands. It is located in Voorne-Putten, South Holland. The former municipality covered an area of of which was water and it included the population centres of Nieuw-Helvoet, Nieuwenhoorn, and Oude en Nieuwe Struiten, all former municipalities. Hellevoetsluis is located on the Haringvliet with the sea, beach, and dunes close by, on the extreme southern edge of the Rijnmond and Europoort areas, close to the broad Zeeland landscape. The name translates as "lock at the foot of the Helle". The Helle was a small local river that disappeared over time. On 1 January 2023, the municipality of Hellevoetsluis merged with Brielle and Westvoorne into the new municipality of Voorne aan Zee. History The area has been settled since before Roman times and was concentrated around a body of water called the "Helle", which was later Latinized by the Romans to "Helinium" and "Helius". The name Hel(le) Voet, Helius' foot or "(land at) the lowest point of Helius", appears in documents from the 13th century and later, such as in 1395, when the Nieuw-Helvoet Polder is issued for inspection. This polder had a drainage sluice (Dutch: "sluis") in the southern dike: the Hellevoetse sluis. The history of Hellevoetsluis has always been connected with water. During the time of the Eighty Year's War and the forming of the United Provinces Hellevoetsluis was the naval port of the Admiralty of de Maze (Rotterdam) and could accommodate an entire fleet within a special land-enclosed fortress with harbour and dockyard facilities, accessible through a canal. Thanks to its strategic situation the town grew from the beginning of the 17th century to be the homeport for the Dutch war fleet. In later years the port was fortified more and more and Hellevoetsluis, therefore, became a unique combination of a fortified town and a naval port. The Admirals Maarten Tromp, Michiel de Ruyter, and Piet Heyn had their home base here and in 1688 during the Glorious Revolution William III of Orange's invasion fleet departed from the port. The Voorne Canal Kanaal door Voorne was built in 1830 from Hellevoetsluis to Nieuwesluis (near Heenvliet) and made Hellevoetsluis an outport of Rotterdam. It was a period when the town grew and flourished; the shipping industry provided prosperity. Its neighbourhood may have been named after a vlotbrug constructed over the canal. In the first half of the 20th century, however, Hellevoetsluis went into decline. Ocean-going ships became too large to use the canal and the Nieuwe Waterweg was dug, making the Canal through Voorne redundant. The naval base was relocated to Den Helder in the 1930s, the Government shipyard was closed, and during World War II the Germans destroyed three-quarters of all buildings in 1944. They also used the canal as a base for Biber submarines. After World War II Hellevoetsluis grew considerably. As a New Town, the population doubled in the 1970s. Today 43,000 inhabitants live in modern houses with abundant green areas nearby. It is home to many commuters
