Fort in de Botshol

Fort in de Botshol is a 19th-century fortification made of earthen walls built on stabilized sand in the Noorderpolder area. The structure consists of ramparts and ditch systems arranged in a compact defensive pattern typical of the era.

This fort was built in 1895 as part of the Stelling van Amsterdam, a defensive line designed to protect the capital. Construction stopped after World War I when advances in military technology made traditional earthwork fortifications less practical.

The name reflects the peat bog landscape that surrounds it, and visitors can see how water control and defense worked hand in hand. The earthen design shows how the Dutch treated water and soil as strategic tools rather than separate elements.

Access must be arranged in advance with Natuurmonumenten, as the site is not open without permission. The annual Open Monumentendag in September is the main opportunity for visitors to explore the grounds.

Unlike other fortifications in the Stelling van Amsterdam, this one was never upgraded or altered after completion. Its original earthwork design from 1895 remains intact, making it one of the few preserved examples of an unmodified defensive structure from this defensive line.
