Been a while since I visited this place, as it's now in private hands, should be fine to post 
It caught my eye when mooching about near my local barracks, and at the time I asked if anyone on here had any ideas what it was, and you did
Turned out to be a U-N-I-T-E-R bunker, really looked different from the images I'd seen of 'em, this one was obviously camoflauged somewhat.
These vents are apparently the giveaway
Secure entry system was what first intrigued me :
So back I went, and in I went
Plant rooms first, loads of kit here, including brand-new water-purifying kit still wrapped :
Proper genny
Corridor shot
Decontamination room :
Ops room I guess:
Comms room, with emergency exit :
Random room - place was fairly stripped :
Proper doors too
That's about it, sorry the pictures aren't the best, twas a point and click job, tripod and long exposures weren't an option here..
