At a height of over 120 meters, the ruins of the former NSA listening station are home to around 2,400 m² of street art – Europe’s largest open-air gallery with over 400 works

An unfinished mountain in Berlin's Grunewald forest, built from the rubble of 400,000 buildings and once used as a Cold War listening station by the US NSA, has been transformed into Europe's largest open-air street art gallery. Since opening to the public in 2011, Teufelsberg now hosts over 400 works across 2,400 square meters, featuring artists such as El Bocho, Nina Valkhoff, Hera, and Dan Kitchener. The site operates as a curated exhibition space with admission fees, guided tours, and regular new commissions, and has been a listed building since November 2018.
