Almost every underground station in Amsterdam has a fascinating story behind it. My favourite one is metro station ‘Weesperplein,’ because it has a hidden station underneath the actual station that was meant for the 'Singellijn.' However, that line was never build and the second station remained useless. Besides that the hidden station was also equipped to serve as a shelter during the cold war. The large doors that were meant to hermetically close the building are still visible at both ends of the platform. Other small details, like the panels in the ceiling than can be used as tables when turned around, are also silent references to the building’s former use.
Under the city, the extraordinary Gesamtkunstwerk by Louis van Gasteren, Jan Sierhuis and others is located in Nieuwmarkt underground. This is one of the public artworks of the Seventies and early Eighties endangered due to station renovation on the Underground Eastline. At present there is a notice hanging at different spots on the wall: ‘‘This artwork has been temporally removed due to renovations”.
