Fort benoorden Spaarndam

Fort benoorden Spaarndam is a military fort with earthen fortifications and a bomb-proof building within the Defence Line of Amsterdam. The structure was completed in 1901 and served as part of a wider system of fortifications protecting the region.

The fort was built in 1901 as part of Amsterdam's defense strategy, which relied on strategic flooding of the surrounding area. It played a role in protecting Slaperdijk and nearby areas during the tensions of the late 1800s.

The interior walls display more than 200 murals painted by Dutch and German soldiers during both World Wars. These images show portraits, cartoons, and scenes of military life, offering insight into how soldiers spent their time during those years.

Visitors can reach the fort by hand-operated ferry across the ringvaart, offering a brief but memorable crossing. Check conditions and opening times before visiting, as the site sits in a rural area with limited services nearby.

The fort remained largely untouched for about 50 years after 1950, preserving its original state and turning it into a time capsule of sorts. Major restoration work only began in 2018, when the roof was renovated to protect the structure.
