The headquarters had an enormous communication bunker. A guided tour brings you many details of the construction and equipment. Directly after the war the Sovjet army stripped most of the technical parts. As from 1960 the now flooded bunker was pumped dry and the bunker was made suitable for the use as a nbc protected commandpost.

After 1994 is was used for historical guided tours and today it's a musuem in development.
