About Stelling van Amsterdam
The Stelling van Amsterdam is a 135-kilometre (84 mi) fortification line around Amsterdam, which would function as a national redoubt. It comprises 45 forts, as well as dams, dikes, locks, pumping stations, batteries and casemates. The forts are 10–15 kilometres (6.2–9.3 mi) from the centre and lowlands, which can easily be inundated in time of war. The inundation was designed to give a depth of about 30 centimetres (12 in), too little for boats to cross. Any buildings within 1 kilometre (0.62 mi) of the line had to be made of wood so that they could be burnt and the obstruction removed.
