Yep. Its another Portsdown Main report. But its my first explore, so I thought I should mark it with my first report.

I have been waiting to do my first explore for a bit now. And after failing to find someone to tag along with and waking up to some great weather. I decided to pick up my point and shoot cam and some other gear, and go solo.

I decided to visit a building that has been looking down at me from atop the hill on a daily basis.

Portsdown Main is an impressive art deco style building which dominates the north Portsmouth skyline sitting atop Portsdown Hill. The building was designed back in the 30s but was never actually built until the 50s, eventually housing Admiralty Signals Establishment (ASE) Admiralty Surface Weapons Establishment (ASWE) Defence Evaluation and Research Agency (DERA) and finally Defence Research Agency (DRA).
As has been mentioned on other reports, the building has been gutted! Was a bit of a shame as all the rooms looked the same. Here goes!

After finding a way in, I got out my cam and did my best photographer impersonation.


Portsdown Main


The rear


Some kind of attempt to keep people out



Looks like a war zone



Main stairs


Main entrance


I found a few of these. They look like a walk in safe or panic room. They have a "fiber-optic communication" link next to them, so maybe a refrigerated server room?



Looks like someone has been crashing here. Just after I found this I heard what sounded like distant foot steps and talking. I thought that its was a patrol doing a room to room search and saying "clear" every few seconds. Don't know what it was but it gave me a good buzz.



The horror!


Don't think it will work.



Filling room


Basement level. It was pitch black and I didn't have a torch :banghead (I'm still learning) Wonder what is down there?

All in all not a bad way to pop my cherry. Cheers for viewing. :thumb
