Fort bij IJmuiden

Fort bij IJmuiden is a fortress on an artificial island in Velsen, protected by a dry moat and equipped with multiple gun positions. The structure displays a triangular layout with thick concrete walls that house underground tunnels and casemented chambers inside.

The fort was built between 1881 and 1888 to guard the entrance of the North Sea Canal against attacks. During its peak operational period, it housed up to 325 military personnel.

The fort is part of the Amsterdam Defense Line, a UNESCO World Heritage site that demonstrates Dutch military engineering from the 1800s. Visitors can walk through the historical spaces and understand how soldiers lived and worked within these walls.

Visitors reach the fort by boat from IJmuiden harbor, with guided tours available to explore the underground tunnels and fortified structures. It is important to wear comfortable shoes, as paths across the island are uneven and access to some areas requires good physical condition.

The fort became an island in 1929 when canal expansion works separated it from the mainland. This transformation fundamentally changed its appearance and turned it into an isolated landmark in the waters off IJmuiden.
