Dutch Water Defence Lines.

The Dutch Water Defence Lines, a UNESCO World Heritage site since July 2021, represent an extraordinary 200 km defensive network that includes the Defence Line of Amsterdam and the New Dutch Waterline. This historic system, developed from 1815 to 1940, showcases advanced hydraulic engineering, featuring forts, dikes, sluices, canals, and inundation polders that allowed for strategic land flooding to deter invaders. Visitors can explore this remarkable heritage through walking routes, cycling paths, and boat tours, immersing themselves in both its military history and innovative water management techniques. The lines not only highlight Dutch ingenuity in defense strategies but also reflect the longstanding relationship between the Netherlands and its water-rich landscape.
