Yes that's definitely a factor, they get "power" from them, they also encode things like pentagrams etc in those big cities, London / Washington DC have enormous pentagrams built right into the street layouts with grand monuments at each point, pretty freaky stuff... The key shape of the vatican is also an esoteric symbol found all over the world.
I could speculate... The Satanic infiltration of new Nations stemmed from Colonial times, Old family bloodlines in Europe (deep state to the normies) secret societies etc build monuments to Esoteric gods like Ra and Moloch (they are Satanic). Satan does not care if you worship or build monuments to him, his goal is to have you worship anyone but God. Im at work so this is off the top of my head.
Ancient Egyptian monument to the sun god Ra, (his dick) In these parts of the ancient world, obelisk like structures resembling the human penis were built, often with phallic symbols, representing human fertility and asserting male sexuality and orgasm.
