The two glass pyramids in Søndermarken is more than just two beautiful architectural constructions. Underneath them you'll find Cisternerne that used to provide the city of Copenhagen with water, and helped solving the major water supply problems during the 1800's after the cholera epidemic. Now it’s a well hidden gem used for various exhibitions. Darkness is the first thing you meet when you walk down the stairs to this 4000 square meter big underground exhibitions space. And not only does this place tease your eyes, it demands you to open up to all of your senses in a way that fewest places does. You won’t know the deal, until you feel it on your own body.
