Pampus

Forteiland Pampus was built between 1887 and 1895 on an artificial island in the IJmeer as the seaward strongpoint of the Defence Line of Amsterdam, the ring of forty-odd forts and flooding works around the city that is on the UNESCO list. It is an armoured fort: a concrete and iron structure with two rotating turrets, designed to close the last open approach to Amsterdam when the surrounding land was deliberately flooded. It was effectively obsolete by the time it opened, since artillery had already outrun its protection, and it never fired in anger. The name comes from the shoal it stands on, which sailing ships had to wait for the tide to cross - the Dutch expression voor Pampus liggen, to lie before Pampus, means to be laid out flat, and comes from that waiting. It is reached only by ferry and has a restaurant and events.

History

The fort stands on an artificial island on the old Pampus shallows of the Zuiderzee, where ships once had to wait for high tide before entering Amsterdam's harbour, which gave Dutch the phrase for lying knocked out, voor Pampus liggen. Work began in 1887, sinking 3,800 piles and bringing in 45,000 cubic metres of sand, and took eight years and 800,000 guilders; commissioned in 1895, the brick and concrete fort carried four Krupp 24-centimetre guns in two hydraulic cupolas and was one of only four forts of the Defence Line of Amsterdam with heavy guns. It had room for a garrison of 200, reached only in the First World War, received anti-aircraft guns in 1926 and never saw action, and when the Afsluitdijk of 1932 cut the IJsselmeer off from the sea it lost its purpose and was abandoned by the army on 15 July 1933. In 1996 the whole Defence Line with its 42 forts became a World Heritage Site (Wikipedia, Pampus).

The main sights

Things to know

Ferry only, seasonal, weather-dependent, and it books up - there is no other way on or off. Interiors are cold and damp. Events sometimes close the island to general visitors.
