http://www.subbrit.org.uk/rsg/sites/s/skendleby/ was turned into a datacentre now run by GCI but previously known as SmartBunker.

Circa 10 years ago I was involved in a project helping transition it from 80s phone exchange into a modern facility built to a good spec. Getting connectivity out there was painful and expensive; at one point it was backhauled wirelessly to Skegness!

Barnton Quarry bunker in Edinburgh (about 4 km west of where I live) is being renovated and will hopefully be open soon:

This bunker would have been the Regional Seat of Government for Scotland:

Given that its location and purpose wasn't a secret I imagine it would have been blown to bits in any conflict.

I was under the impression that the RSGs were secret until 1963 when an anti nuke campaign group exposed them?

But then, hey, Britain. We have a load of secrets that aren't technically secret but we'd rather you didn't know and would take a dim view of you trying to find out. Especially true during the Cold War (see e.g. Backbone, etc).

Good point - I'm not sure when Barnton stopped being the RSG - I had assumed it was well after '63.

There was a new RSG type bunker at Cultybraggan near Comrie but, with impeccable timing, that wasn't completed until 1990!

Outside of Houston, Texas, this former private bunker (http://www.houstonbunker.com/about/) was turned into a secure data warehouse. I believe Continental Airlines used to use it for their data.
