Frederiksberg, Denmark


A 19th century subterranean reservoir repurposed as a contemporary art cave. 

Some of the most avant-garde contemporary art in Copenhagen is quite literally underground.

Cisternerne is an old subterranean reservoir that supplied drinking water to all of Copenhagen from the 1850s until the 1930s, and also doubled as a reflection pool for the nearby Frederiksborg Castle. When the cisterns were finally drained and covered in 1981, they were used as an exhibition space for modern glass art for a decade before they were adopted into the Frederiksborg Museum.

Today, Cisternerne, which lies below the grounds of Søndermarken park, functions as a multimedia installation space. The only indication of its presence are the two towering glass pyramids that mark its entrance and exit points. Descending into the dripstone cave (the only one of its kind in Denmark) the atmosphere changes drastically. The air is typically at 100% humidity, but the temperature is usually a cool 47˚F. Impressive stalactites and stalagmites extend from the floor and ceiling, but it’s the art people come to see in this unique setting.

The Frederiksborg Museum commissions an artist to create an exhibition for Cisternerne every year. The artists use the unusual cavern setting—along with its darkness, humidity, and reverberant acoustics—to create equally unusual art. The dark, dank series of tunnels prove to be an excellent, if sometimes creepy, backdrop for light and video installations. The installation in 2017 will include a mossy replica of a 6th century Japanese shrine by Hiroshi Sambuichi.

Know Before You Go

The entrance to Cisternerne is located in Søndermarken just across from Frederiksberg Palace and the Copenhagen Zoo. The entry is located in a pyramid of glass (see photo). As the cisterns are naturally very damp, waterproof shoes are highly recommended. Also be prepared for a temperature drop once down in the tunnels, and be aware of the presence of lye in the water.
