Lunetten op de Houtense Vlakte

Lunetten op de Houtense Vlakte consists of four identical crescent-shaped fortifications built on raised ground near Utrecht. These structures are connected and form an integrated defensive system with water-filled moats and earth ramparts.

The fortifications were built between 1819 and 1826 as part of the New Dutch Waterline, a defense system designed to protect Utrecht from attack. This construction period followed the Napoleonic Wars when the country reinforced its defenses.

The fortifications display Dutch military design through their combination of water systems and defensive structures. These crescent-shaped forts were built to work together as part of a coordinated protection strategy for the region.

The four forts are accessible on foot and open for visits throughout the year. Some buildings now house community organizations, so certain areas may have limited access during their activities.

Fort Lunet I contains an atomic shelter built in the 1950s that served as a Civil Defense command center during the Cold War. This underground structure is a rare example of Cold War-era protection planning.
