Nasses Dreieck, Free area in Pankow district, Berlin, Germany

Nasses Dreieck is a free-access green area where three Berlin districts meet: Gesundbrunnen, Prenzlauer Berg, and Pankow. The space consists mainly of grassland and mixed plant communities.

This site emerged from a former border strip after the Berlin Wall fell and was gradually transformed into a natural space. Protected landscape status came later as the area's ecological value became recognized.

Local residents actively maintain and use this space, treating it as a community gathering spot worth protecting. People have worked together to ensure it remains open and accessible to everyone.

The southern entrance near the S-Bahn station is open to foot traffic and cyclists. Expect varied ground conditions throughout the area, so sturdy shoes are recommended.

Fifty sand lizards, each up to 20 centimetres long, live on the grassland. Deutsche Bahn staff caught them one by one with nets on other construction sites and released them in a fenced strip along the tracks toward Pankow station.
