Built during WW2. The main part of the shelter, over 30m underground, consists of a pair of parallel tunnels, just over 5 meters in diameter and 370 meters long. The shelter was designed to accommodate up to 8,000 people!

Each main tunnel is subdivided into two decks...

This was literally a flying visit, wish we'd stayed longer, we'd already spent 5 hours in the biggest baddest drain in the UK that evening.

Having not been in the shelter long, we bumped into some other explorers who were on their way to Abbey Mills Pumping Station, so we tagged along. Unfortunately this was uber as access has been sealed!

Thanks for looking
