"As an extension of Copenhagen’s Frederiksberg Museums, the Cisternerne operates as a venue for exhibitions and events—but it’s the space itself that is the permanent exhibit and primary attraction. Once a subterranean reservoir filled with 16 million liters of water, the cistern has been filled by an unconventional museum. The cryptic underground cave—the only dripstone cave in Denmark—is a gloomy labyrinth filled with stalactites and stalagmites." - Mary Holland, Jenna Scatena
