It’s hard not to notice the historic water reservoirs toppling over Prenzlauer Berg’s Kollwitzplatz, but few know that these structures have hosted summer-long programs of installations and performances from internationally renowned sound artists since 2007.

A focal point for Berlin’s vibrant sound-art scene, Singuhr often commissions new work specifically for the space. The underground chambers brandish an entirely unique architecture made more dramatic by the cold, murky atmosphere and uniformly bricked curvaceous walls. The overall effect is haunting and magical, especially as one wades through the tunnels followed by the cannoning sounds of their own footsteps.
