Fort Nieuwersluis | World Heritage the Dutch Waterlines - Nieuwersluis

N 52.1933256 / E 5.0015828

UNESCO World Heritage The Dutch Waterlines tells the story of the strategic use of water in the defence of the Netherlands. The water lines were also called the secret weapon of the Netherlands.

Secret weapon
In a waterline, water is used to stop the enemy. A system of locks, dykes, canals, rivers and pumping stations ensured that entire polders could be flooded. The layer of water was only 40 to 50 centimetres. This was too deep to walk and too shallow to sail. At vulnerable points, forts were built for extra protection. Many of these forts can be visited.

In 2021, UNESCO World Heritage The Stelling van Amsterdam (World Heritage since 1996) will be expanded with the Nieuwe Hollandse Waterlinie to complete the picture of the Waterlinies as one World Heritage Site - the Dutch Waterlines.

Part of the Dutch Water Defence Line is Fort Nieuwersluis, a special green World Heritage between Loenen and Breukelen. In and around the Fortress, work, culture, recreation and nature go hand in hand. There are five beautiful office spaces at the fortress, as well as several rooms that can be rented for events, meetings, workshops and private dinners or high-teas. Every Sunday, the Fort Nieuwersluis Tea Garden serves coffee, tea, juices and other delicious homemade dishes.
