That bunker must be Scotland’s worst-kept secret. It is signposted all over a huge area of the south-east of the country, presumably because, being right in the middle of nowhere, it would otherwise be quite difficult to find (and that probably was part of the original idea).
It’s actually worth visiting if you’re into Cold War history. The interior is a weird hodge-podge of stuff that is to do with the actual bunker and its use and other stuff that just seems sort-of interesting to military buffs (yes, we’re pretty sure the bunker occupants would have defended themselves with the WWII-era Soviet machine pistol on display in the bunker’s “armoury”). If they could find a cannon from the Battle of Trafalgar they would probably put it in there just because they could. But the site itself is really kinda amazing in a morbid way; who, having diligently charted all the impacts of nuclear warheads from the relative safety of the bunker, would want to sit in the thing for years waiting for the radioactivity up top to subside, in order to emerge to find … what exactly?
