In 1997 , following the decision to move the capital and government seat of re-unified Germany to Berlin , it was decided to abandon the bunker as no concept for civilian use could be found . Only few parts of the fire safety installations had been upgraded , which was a decisive criterion that deterred potential investors . The costs of continuous operation of DM 20 million ( about EUR 10 million ) , however , could have been reduced in event of civil use as preparations for potential nuclear attacks would no longer have been required . It also would have been possible to use only one of the five independent sections . Over the following years the tunnels were cleared out , gutted and sealed , costing € 16 million in total . In 2001 deconstruction was interrupted briefly due to considerations whether it might be sensible to have a bunker following the September 11 attacks . All that remains now are the gutted , concrete-lined tunnels . The access buildings above the '' Kloster Marienthal '' vinyard still exist , although the doors have been welded shut
