Fort aan de Drecht

Fort aan de Drecht is a military fortification in Uithoorn built on an artificial island with thick concrete walls that command the waterways. The structure strategically uses surrounding rivers and water channels as part of its defensive system.

The fort was built in 1911 as part of the Defence Line of Amsterdam, a network of roughly 96 fortifications surrounding the capital. This defensive network represented an innovative approach to protecting the city from invasion.

The fort embodies Dutch engineering and water management skills, recognized as part of a UNESCO World Heritage site protecting the capital. Visitors can observe how these practical abilities shaped the building's construction and positioning.

Visits are possible Thursday through Sunday, with dining and event facilities available on site. Free parking is located a short two-minute walk away.

Inside is a curved armor plate made of nickel cast steel weighing 26,000 kilograms with 20 centimeter thickness. This massive steel component shows the technical sophistication built into the defensive structure.
