This is the story of a secret underground wartime factory in a very unusual place in Britain's capital. Interesting Sh!t's Steve Hulford had a chance to visit.

Join Steve on a tour through the tunnels of Gants Hill tube station in London, UK. During WWII, the station was used as an air raid shelter and the tunnels as a munitions factory for Plessey electronics. Plessey opened their facility in 1942, and production lasted until 1945 before the station was opened for public transport on 14 December 1947.

I am insatiably curious about our world, and the people in it. I grew up getting lost in the pages of National Geographic, the World Almanac, Ripley's Believe It Or Not and various World Atlases. This thirst for knowledge has led me on various adventures around the world. I have been fortunate to travel to over sixty countries, and met countless interesting characters. Nepal is one of my favorite places in the world.
