    Hiking

    In the Schwarzer Grund there is a large boulder, the so-called Thielstein, which has been designated a natural monument of the city of Berlin. It is the largest boulder in Berlin, weighs 50 tons and has a circumference of ten meters. It was found during the construction of the Freie Universität subway station (Thielplatz) and it took 14 days to move it from the excavation pit around 40 meters to its current location using cable winches.

    Hiking

    In 1912, the Prussian capital built a subway line from Wittenbergplatz to the upscale district of Dahlem. During excavation work at the new Thielplatz subway station, construction workers discovered a 50-ton boulder, which at 10.10 m in circumference is the largest stone ever found in Berlin. It took the engineers two weeks to move the boulder 40 meters away from the route, where it still lies today.
