underground

First visit and upload to this website. Decided to go to a fort that hasn't had many posts about it. We managed to look around the outside of the fort, finding many old buildings and rooms of such. However, we did manage to see a corner of the fort that seemed to look unusual, so decided to...

Does anyone know of any accessible tunnels in or around Brighton? Want to experiment on lighting tunnels for a project. I'm aware of the one from Brighton Pavilion to the Dome and various access tunnels to the beach, as well as the disused Kemptown railway tunnel and an of air raid shelter. Any...

Hillhead Tunnel is located in Northern Northumberland; near the rural village of Edlingham. Built in the 1880s, It was once used to bypass a steep gradient in the landscape to ensure trains could continue travelling safely on the now disused, abandoned and overgrown Alnwick to Cornhill line...

I know, this one has taken me an age to post, but in my defence right after this one I got quite sick, moved to a different county and changed jobs all in the space of about 6 weeks! Anyway, enough about my personal life, that's not what you're all here for! Here's the explore. History: When...

We recently explored the surrounding area here, as it is MOD property there are some strange rules. It seems to be fine to walk through, but the person who told us about this place said if you stand around too long some military police show up and move you on. The areas circled are X2 entrances...

This was my first ever underground explore, and I have to say I felt a sense of trepidation traipsing through the woods at night with a head torch on following my two friends. It was cold and I was quite convinced we weren't going to find it until there it was, the entrance appearing from the...

I've been meaning to post this explore for some time now, 2 years later and here it is This is my first explore and so I will keep it brief as I know there are many more comprehensive reports on this site. You are greeted by a vast undulating rooftop with access points dotted around, beneath...

Shedload (a.k.a a big ol detention tank), Bristol So first off I should say that this isn’t exactly an ‘ep1c’ or anything, don’t get me wrong. It is, however, something that has been a bit of a thing of conversation over the years as far as talks of Bristol underground go. The only...
