The Cisterns - museum in Copenhagen, Denmark. Tanks are an integral part of the Frederiksberg Museums and serve as a venue for art exhibitions and other events, where the uniqueness of architecture and atmosphere remains the main attraction.
The Cisterns: a cave in the city Located under the Fredericksberg Hill in the heart of Söndermarken Park, Tanks is the only dripstone cave in Denmark. The natural formation of stalactites and stalagmites is not unusual for concrete structures, but no one anywhere can offer the obvious scale and variety of those found here.
In February 2009 Forbes called the Cisternern one of the most unusual exhibition spaces in Europe.
The Cisterns, a long-forgotten underground reservoir, once served as a source of drinking water for the Danish capital and contained up to 16 million liters of clean water. Excavations began in 1856. It took only three years to complete, and this huge structure quickly helped to solve many problems with water supply at that time; but by 1933, the city's cisterns ceased to serve as a drinking water tank, and they were finally drained in 1981. In 1996, due to Copenhagen's status as a European cultural city - and thanks to a joint initiative between the city of Fredericksberg and gallery owner Max Seidenfaden, who managed the tanks as a museum of modern glass art from 2001 to 2013 - the underground water tank was used as an exhibition space.
