Labyrinth has always been a subject of heated debate. Confusion as to its route, its integration and interaction with other sewers and also as to where the line should be drawn between itself and other systems. On a map it looks like a tangled spiders web of incomprehensibility, and with the knowledge of the area at the time, we likely made things worse with our assumptions.

Deep Ochre. If I’m honest, this was the one. I first saw it on Sub-urban back in 2006, before that i didn’t have a whole lot of interest in drains. I had seen pictures of the Westbourne and other various tunnels and culverts, but this just looked, different.

Another one of those explorer defiant ue sites. Every single door was locked inside and out, every window blocked and screwed shut, plus several barbed bendy fences. Combine that with the fact its on a live site and has a jumpy security guard who will call the police at the slightest incident and you have a real pain in the arse.

Macro, Bradford. What an impressive mix of old and new, including several truly impressive pieces of British architecture and design. There is only one downside to all this. Being a culvert in the north, the floors once constructed with stone or brick have been ripped up during storms and heavy rainfall and now lay in a mess, an assault course to the unwary traveler. One that proved to much for me the first time around. Earning me the timely badge of “Teh Otter”.

The final explore of what was an exhausting weekend. After a brilliant trip this was the perfect way to finish. The building currently stands at 187 meters high, with the crane towering over the building, I am unsure at to the total height probably around 670-700ft but either way its the biggest structure I would have climbed.

The first stop on the two day Paris trip. The tunnels were built by the Germans in world war II to house and store their V2 rockets and associated trains that launched them, although it is unsure if they were ever used or not. The first striking feature is easily the size. They are huge, easily the biggest underground space I have explored.
