The bunker in Machern is the only almost completely preserved district Stasi secondary command station.
In 1968, the office of the Leipzig Stasi chief Manfred Hummitzsch was moved together with staff from the district administration in the "round corner" to Machern, so as to maintain the control of the SED regime. The system, which is still in its original state, explains its history, structure and working methods in the course of its exhibition.
