Germany·May 27 - 28 2023


Experience climbing and urbex culture in one of the most vibrant cities in the world: Berlin!  Organised by Fjello.



Klettern am Beton, literally "climbing on concrete", is the experience that Fjello propose! Inspired by a publication by three german climbers (Veit Althoff, Jonas Jägermeyr and Christian Wahle), "Am Beton". This experience combines underground culture, urbex and climbing in one of the most vibrant cities in the world: Berlin! As a flat city, Berlin may not seem like an obvious hub for climbing culture, but in recent years it has emerged as a thriving scene for bouldering and rock climbing enthusiasts, with several indoor and outdoor climbing facilities available for enthusiasts. Outdoor climbing is particularly exciting in Berlin, as the city has a number of abandoned buildings and structures that provide unique and challenging climbing opportunities. Indeed, you'll have the opportunity to climb World War II bunkers. These abandoned structures provide a unique and challenging climbing experience that you won't find anywhere else in the world...

The Experience





Humboldthain Flank Towers

Humboldthain Flank Towers are two historic flak towers at the top of a World War II air-raid shelter, a monstrous concrete structure from the early 1940s that offers a singular view of the north of Berlin.

These massive concrete structures are now a great location to climb offering climbing walls that are managed by the German Alpine Club!

After the climb, you'll have the opportunity to visit the interior of the tower. In the evening we can move in Friedrichshein, a vibrant neborhood in Berlin where you can also climb Der Kegel that is over 18 metres high. 



Koralle Lager

40 mins away from Berlin, there's another interesting bunker.

Koralle Lager was the code name of a military facility north of Bernau near Berlin, in which 1943-1945 the command center of the High Command of the Navy (OKM) and the radio control center for the submarine war was located.

The programme is very flexible to take into account weather conditions, activities level and endurance of the group.
