Bunker Kagel

Bunker Kagel is an underground facility in Grünheide that served as a listening post during the Cold War. The structure consists of three levels with rooms for radio equipment, switching systems, and administrative areas that were buried below ground.

The bunker was planned in the late 1950s and completed in 1961 as East Germany expanded its surveillance network. The structure was built during a time when political tensions between East and West were steadily rising.

The site was part of East Germany's surveillance network and shows how authorities wanted to monitor communications during that era. Visitors can see rooms where people once sat at radio equipment monitoring messages.

Visitors should expect tight underground spaces and limited lighting that reflect the working conditions of that time. Sturdy footwear is recommended since the corridors are uneven and the temperature beneath the ground stays cool.

The bunker was equipped with advanced radio technology that was specifically developed for long range and secure communication. Some of these technical solutions were remarkable for their time and show the technical capacity that existed in such facilities.
