tunnels

History Located under Brownes Folly (a small tower commissioned by Wade Browne, at the time the quarry owner, in 1848) sits a huge network of tunnels originally dug to extract the unique high quality and easily-carved Bath stone the area provides. Originally, the area was quarried at a small...

1. The History The Esplanade tunnels are situated under Dover Castle in Kent and run along the base of the cliffs, between the Eastern Arm of the harbour and Dover town centre. They date back to the 1800s and originally were a cave system. They were subsequently expanded during the Napoleonic...

February 2026 I ticked these two off over the course of two visits in an effort to finish exploring all of Oldham’s railway tunnels. My first attempt was on a Saturday afternoon, which turned out to be a mistake — the tunnel was absolutely infested with what seemed like every child in Greater...

Another one from that same weekend in Kent in 2023 spent exploring Esplanade and Christ Church Air Raid Shelter. This one is close to where my friend lives and seemed line a good little mooch before I headed back home to Luton. We only saw a small part of it, but it was a nice little explore all...

A visit from the same day I visited Chrit Church Air Raid Shelter. The Esplanade tunnels were open on the same day, so it felt rude not to visit as I missed out on it previously! The tunnels at Dover Esplanade have history dating back to the 1800s and expanded upon during the Napoleonic era...

On a misty day in Dover decided to try these tunnels out for an explore. The Dover Esplanade Tunnels, originally built for Napoleonic troops and later expanded into crucial WW2 command centers, hospitals, and Cold War shelters, though Level E (Esplanade) was primarily an air-raid shelter and...

As is the same with many of you my main fascination is with underground bunkers, tunnels and other undergound buildings. As such I was watching a video last night about how many many cities across the world have old cities underneath where full buildings are intact under the new buildings. The...

RNAD Milford Haven Part 2 : The tunnels and Surrounding Area. 26/12/25 Boxing Day. The path leading to the underground tunnels were far more accessible this time around. I didn’t explore the whole tunnelling system because I was on my own. I found 5 out of 6 of the tunnels, 3 of them being...

A small one from me that has been on the list for many, many years, but I've never bothered. I popped in as I was in the area already and fancied something whilst I was there. It was very easy to locate, but my lanky frame meant climbing across the twisted mess of RSJs meant I had to twist in...

We popped in here while in the area looking at some bits, it really hasn't changed in years this place. Topside is completely trashed but it was good tick off the underground tunnels and a good reason to waste an hour or two messing around with some lights underground History The Royal Naval...

History: The Bidston Hill tunnel project was born in 1941, probably out of the devastating effects of the Luftwaffe blitz on Merseyside. During these dark months many infrastructure targets were hit, many people were killed and many more made homeless. The first week of May 1941 saw the peak of...
