Cisternerne (The Cisterns)

Cisternerne is an underground cistern complex beneath Søndermarken in the Frederiksberg area of Copenhagen that has been adapted into an exhibition space for contemporary art. As part of Frederiksberg Museums (Frederiksbergmuseerne), it hosts an annual site-specific total experience and a range of events throughout the year. The supplied sources emphasize the site's distinctive architecture and atmosphere as core attractions and do not provide construction dates, detailed engineering history, or precise coordinates. The source material consulted (Wikipedia and Wikidata entries) contains no reports of paranormal activity, hauntings, apparitions, auditory phenomena, or named supernatural entities connected with Cisternerne. There are also no folkloric traditions or local supernatural narratives referenced in the provided material. Because the site's primary notability in the available sources is architectural and cultural—specifically its use for contemporary art exhibitions—no speculative interpretations of unexplained phenomena are included.
