Uncovering hidden histories in Berlin's underworld

Old bunkers, tunnels, secret passages and the many tales they have to tell … If you're up for going down into the depths of Berlin, you'll be amazed by what you discover.

There are a number of places in Germany where you can unlock all kinds of secrets. To unearth some of the most fascinating stories, head to the capital city. There's much more to Berlin than what you can see from the ground up. Below its surface, Berlin is as full of holes as a Swiss cheese: hidden away beneath the wide streets and squares, there lies a series of secret passages and tunnels and other incredible remnants that reveal the city's turbulent past.

From its base in a heritage-listed bunker north of Museum Island, the Berlin Underworlds Association has been working since 1997 to safeguard these historically significant structures. The organisation researches, documents and preserves the infrastructure of subterranean Berlin and is gradually making it more accessible to the public. Its permanent multimedia exhibition also sheds light on architecture and urban development in Nazi-era Berlin, enabling visitors to make their own journeys of discovery.
