Teufelsberg, or 'Devil's Mountain,' is an artificial hill in Berlin, standing at 120.1 meters above sea level. It was constructed from the rubble of World War II and is now one of Berlin's highest points. The site is historically significant due to the abandoned Cold War listening station used by the US and British forces to intercept Soviet communications.

Teufelsberg offers a unique combination of history, art, and nature. Visitors can explore the graffiti-covered ruins of the listening station, enjoy panoramic views of Berlin and the surrounding Grunewald Forest from the top, and participate in guided tours that provide insights into its historical significance. The hill is also a popular spot for hiking, mountain biking, and paragliding.

Teufelsberg's rich history and cultural significance, coupled with its natural beauty and recreational opportunities, make it a must-visit destination for anyone exploring Berlin.
