Set Within an active, secure Bundeswehr site at Wildpark, c. 6 km SW of Potsdam. There are two distinct bunker complexes on the site. There is an active signals centre, Fernmeldesystemzentrum , one of five
such interlinked centres in modern Germany, built c. 1980 - 85 to replace the older bunker ('Göring's bunker) nearby, with which it was linked by a tunnel (now sealed.) 

'Göring's bunker - built 1936 - 40 or 42.  Göring's train was kept on a siding nearby. It was used by the Russians 1945 - 56, and the East German Army 1956 onwards being re-equipped 1962 and has been in the hands of the Bundeswehr since 1992 It is now surplus to BW requirements, and is now in the process of being stripped and sealed as it is too expensive to maintain, and to man for frequently requested tours (ours therefore amongst the last) We were invited to take any souvenirs we wanted! 

A cut-and-cover construction, inside a small hill with 25m cover. A very large bunker that could accommodate 160 men for three months with an independent oxygen supplies for two weeks. It was never used for operations
direction in the event of war (? Cold War period) and would have functioned for 20 minutes then closed down.

Coffins of German notables were stored here for a while during WWII hostilities. The bunker is not now ventilated and connections to new bunker are via the emergency escape routes already sealed. Escape routes were tortuous, via machine rooms with restricted headroom with a narrow tunnel for staff and a wider tunnel with many steps for officers!  When Bundeswehr took over there was an orderly exchange of command, but classified material had been destroyed. Items of note inside the bunker include freestanding yellow Russian
submarine air-conditioning unit’s .these are evidently more than simple silica gel de-humidifiers .  they (also) absorbed CO2 and replenished oxygen levels. (We liberated three of these). Most of the plant was still in place.

There were also NVA (National volks armee) surveillance tapes and wooden telephone booth for the 'hot line to Moscow.' In the grounds outside a 'windmill' air raid shelter, and a radiation and blast detector unit which would automatically close the bunker external doors in the event of a nuclear explosion.  Also buried wires to detect EMP.
