Cisterns in Søndermarken

This guide to the Cisterns in Sondermarken follows Copenhagen's 1853 cholera outbreak and the three vast granite chambers carved into Frederiksberg Hill to hold clean drinking water for the city. It traces the reservoir's decades of use, its sealing under a concrete lid, and the accidental process that began once it sat empty and dripping in the dark. Stand still and listen for the drip overhead in the pitch-black chambers.
