Marine Etablissement Amsterdam

1655: Construction of the Naval Warehouse began on an island in the IJ River, which later became the Maritime Museum. A large shipyard for the Admiralty was built next door. After a fire in 1791, it was rebuilt and taken over by the navy in 1795. Until 1915: Production of wooden and iron naval vessels, including the Hollandia and Van Speijk's gunboat. Due to the ships' oversize, the shipyard moved to Den Helder. 1915–2005: The site was used as a training center, storage facility, and military base. During WWII, the Germans seized it. Demolition for the IJ Tunnel followed in 1962. From 2011: The Ministry of Defence sold the site. It was opened to the public in phases, including during the EU presidency in 2016. The Ministry of Defence remained partly for strategic reasons. 2025: Four buildings, including a ship's workshop and officers' residences with a Cold War bunker, are designated monuments. A decision on the nuclear bunker will follow later. Visitors can view, among other things, the 17th-century entrance gate and a number of mounted cannons from a ship from Admiral Michiel de Ruyter's fleet.
