135 km ring of fortifications around Amsterdam
Uitgeest - Centuries ago, during the Eighty Years' War between Holland and Spain, the Dutch resistance began to flood entire areas. This way they could easily defend themselves against the enemy. The flooded areas were too deep to walk, but too shallow to pass. The same idea has been used in the 135 km ring of fortifications around Amsterdam.
