Reception Hall and Vorbunker / Cut

The 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.
