Diorama
In 1970, the Russians expanded their headquarters with a "Diorama": a circular, windowless concrete temple. Due to its dilapidated state, the building can no longer be visited.
Inside hangs - or rather hung - the work of art "Die Schlacht um Berlin," a gift from the GDR to the Russian army. The Russians took the 36-meter-long and 7-meter-high work home with them when they left in 1994.
