Berliner Unterwelten e.V.

This guide to Berliner Unterwelten e.V. in Berlin follows Dietmar Arnold, a young Berliner whose university exchange to Paris and three days among the cataphiles' underground tunnels sent him home wondering what was hiding beneath his own city. You'll hear how he and a small circle of friends founded an association in 1997 to document Berlin's vanishing bunkers and tunnels before construction crews bulldozed them, and how volunteers spent thousands of hours clearing rubble from this bunker beneath Gesundbrunnen station. It also traces what a group of members stumbled on here in the year 2000, buried among the forgotten drawers.
