List of forts

The following forts belong to the World Heritage ‘Defence Line of Amsterdam’. The earthworks, the defensible earthworks and the ‘bomb-free’ buildings of each fort were completed successively in the years listed. ‘Bomb-free’ means that the buildings provided protection against artillery strikes mostly through their concrete constructions. The earthworks were constructed long before the concrete buildings.
