And strange remnant geometry here

Also the Volkshalle, designed by Hitler: “It would still remain the largest enclosed space in the world had it been built. Although war came before work could begin, all the necessary land was acquired, and the engineering plans were worked out. The building would have been over 200 metres high and 250 metres in diameter, sixteen times larger than the dome of St. Peter’s.”

“Although the Volkshalle was never built, critics claimed it might have severe architectural problems, such as acoustics that would (depending on the critic) either make it impossible to hear a speaker, or would magnify the speaker’s voice to such a volume that it might cause deafness.”

Imagine Hitler giving a speech in the Volkshalle to all the 150,000 representatives of his subjigated people that would have fit inside, and the crowd isn’t into it, maybe they’re booing, and he gets angry (have we ever seen him not angry?).  He takes a few steps forward and continues his oration with great force, and proceeds to deafen his audience.  What a dick.
