Hall and Vorbunker / Cut
air raid shelter and the reception hall were designed to
form a static symbiosis. As previously mentioned, the shelter,
with its thick concrete ceiling, formed a solid foundation
for the marble columns in the reception hall. These columns
reached 50 cm downward through the air cushion beneath the
reception hall floor, resting directly on the bunker ceiling.
The placement of the pillars was also determined by the
layout of the shelter. Each pillar was placed squarely on
top of an intersection between two bunker walls. The extra
pressure bearing down on these intersections added strength
and stability to the air raid shelter.
