Defence Line of Amsterdam-Fort Krommeniedijk

The UNESCO World Heritage Site known as the Defence Line of Amsterdam (in Dutch named Stelling van Amsterdam) is a 135 km long ring of fortifications around Amsterdam, consisting of 42 forts located between 10 to 15 kilometers the centre, and lowlands that can easily be flooded in time of war. The flooding was designed to give a depth of about 30 cm, insufficient for boats to traverse. Any buildings within 1 km of the line had to be made of wood, so that they could be burnt and the obstruction removed.

The Stelling van Amsterdam was constructed between 1880 and 1920. The invention of the aeroplane and tank made the forts obsolete almost as soon as they were finished. Many of the forts now are under the control of the town councils and the nature department, and may be visited. Monuments Day, on the second Saturday in September, is the ideal day to visit as entrance is free.

The Fort near Krommeniedijk sits beautifully within the landscape. In 2004 most of the overgrowth was removed, making it easy again to recognize that the structure is a fort. Remarkably, the cooking kettles are still there. The kitchen can be put back to use immediately, so to speak. Another interesting aspect are the gorge casemates at the rear of the fort, featuring range tables and a panoramic drawing that has captured the nineteenth-century landscape. There is a secondary battery to the east of the fort.

Several times a year an open day is held. If you wish to visit the Fort near Krommediedijk on other days, please contact Landschap Noord-Holland. You can also receive an explanation about the flora and fauna around the fort. Because of the breeding season, this is not always possible though. Excursions and guided tours are at a charge.

The Werkgroep Fort Krommeniedijk organizes special activities here. In 2013 a visitor centre about the Defence Line of Amsterdam will be opening at this fort, which will pay special attention to the amazing natural surroundings of the ‘Stelling’.

The Fort near Krommeniedijk served to defend de Lagendijk (dike) between the towns of Uitgeest and Krommenie and the navigable waterway Krommenie. In 1896 the defensible earthwork of this fort was finished, whereas the shellproof building was completed in 1903.
