About Stelling Van Amsterdam
The UNESCO World Heritage Site known as the Defence Line of Amsterdam is a 135 km ring of fortifications around Amsterdam. It has 42 forts that are 10-15 km from the centre and lowlands, which can easily be flooded in time of war. The flooding was designed to give a depth of about 30 cm, too little for boats to cross.
