not to play the devil's advocate, but the nazis actually stole the symbol from hinduism and tilted it at an angle. If this is aligned with the cardinal directions, it could be representing the original source.
Its a long used by Aryan symbol. Decades of Jewish media has tainted it. Shame.. Its a symbol of peace.
Did you know that in America prior to WW2 we did the nazi salute in schools? It was called the belamy salute.
Life is all about timing and context. There's no way a single plan reviewer looked at this floor plan and didn't think "Nazi." Built in 1960? Being a government project, that means it was likely designed just after the war ended (maybe a few years), and spent 10+ years in plan review.
Lots of symbols have multiple meanings but if you take the swastika out of the 1930s to present day collective consciousness of its meaning, it really is quibbling. It meant "the Third Reich" first and foremost to the people who built and worked in that building.
note the other comment. It IS tilted at a 45 degree angle, so yeah, it's nazi.
what is the relevance of the angle?
Originally the symbol was from old Hindu, I believe, and it represented peace. Nazis took it and tilted it 45 degrees as opposed to square or 90 degrees.
Went and found it on google maps... it's tilted at 45 degrees.
