The Defence Line of Amsterdam is a circular defence around the city of Amsterdam which was built by the Ministry of War between 1883 and 1920.
* The army, government and king (or queen) could retreat within this ring in the case of an attack on the Netherlands.
The area around the fortifications is divided into polders, each at a different level and surrounded by dikes. Each polder has its own flooding facilities.
The ring of forts make up a group of connected buildings and other structures, that are well conserved and have remained unchanged. They form the main defence line together with the dikes, line ramparts, hydraulic properties, forts, batteries and other military buildings, and the structure of the landscape.
