I'm sure this has come up somewhere but are there really under ground bases?

Sorry you have to be joking right?

Cheyenne Mountain? And the hundreds of other facilities!

I have visited several here in the UK on an official capacity, we have many.

I know these places exist but where are they in the UK and are there any in Wales?

tobyswansea try a Google search "government underground bases "
most of the AWE Bases have underground sections

I have visited many in the UK, below is listed the ones I can remeber...

RAF High Wycombe - HQ Strike Command
RAF Neatishead
HMS Warrior(Northwood)
Rudloe Manor(Corsham)
Pindar(London)

I know I have been to more but just cant remeber them off top of my head. There actual existence is not as secret as many would have you believe, simply what they do there is!

godatum thanks for the link , i'm on my way to visit each one of 'em now
