Both the East and West entrance were protected with huge sliding
doors. These doors are made of steel with concrete inside and
run on rails. They are 2.5 m thick and weigh around 30 tons each.
The West entrance is where you can enter the building. The door
is in working condition (up to half the entrance) and can be electrically
operated. Leica R8 with Vario-Elmarit-R
