Not sure if this is still being kept out of the public eye or not so il stick it here to be safe, feel free to move 
Visited on our way home from the UK roadtrip with Maniac and Muffie, this was an awesome site and i am so glad to have finally visited it!
The history on this site is relatively scarce, but you can visit this site for a little bit! Portsdown Tunnels - Tunnel Shelters - General
Gotta give a big thanks to Urban-Junky for this, helped a lot!
So after walking through the caravan site pretending to be on the phone talking to myself about trying to find number 16, i grabbed the guys and off we went, covered in bits of various mines, cement works and hospitals! While going in through the entrance an old man started yelling at us saying we 'shouldnt be here', we ignored him and carried on as we were, expecting police to appear, but luckily they didnt
Anyway, on with the pics.
An old stamp on the roof of one of the junctions, hadnt seen a pic of this before, also, sorry for the quality lol.
Thanks for looking!
