Um, yeah. I thought this was kinda well known.
Like how the Soviets built their DC embassy near the top of Mt St Albans, by the National Cathedral, becase it’s the highest point in DC and has direct lines of sight to just about every government facility and foreign embassy in the region, including NSA, CIA, DIA, Pentagon, etc.
Heck, before he died the last few Jack Ryan books Tom Clancy wrote involved a secret agence located directly between the CIA and NSA that had a structure just like this on it’s roof to suck down line of sight microwave and laser transmissions between the two.
