A couple things really stuck out for me. First, it looked like everyone that worked there had literally left for lunch one day and never came back. No orderly wind-down, just instantly abandoned, everything left behind. Second, they had these massive brass waveguides connecting the antennas to rooms of primitive mainframes. I found it interesting that no one had ever salvaged, legally or illegally, the considerable scrap metal value contained in those installations. These buildings have been abandoned since before I was born and there was literally tons of high-value scrap just sitting there.
These places have a strange vibe, they feel ancient. No one really messes with these abandoned places, they are treated like an archaic relic or monument even though they aren’t that old. It is sort of a surreal feeling of coming across the ruins of some dead civilization like some kind of sci-fi trope.
Really damn cool though.
