At the time of its creation, the Hall was a structure with the largest dome span in the world – 65 meters in diameter – overshadowing even the Pantheon in Rome.

Few believed in Max Berg's design and the durability of the construction. There was even a situation in which the construction team, fearing for the stability of the object, did not want to remove the expansion bolts reinforcing the formwork of Hall's ribs.
