The Williamson Tunnels are a labyrinth of tunnels and caverns under the Edge Hill district of Liverpool. They were built in the first few decades of the nineteenth century under the control of a retired tobacco merchant called Joseph Williamson. The purpose of their construction was to give jobs to unemployed men.

Although some of the tunnels have been lost over the years, a lot of them still exist today, under what is now a residential area. The Friends of Williamson's Tunnels, founded in 1996, is a voluntary organisation which is trying to get the tunnels renovated and opened to the public.

On Wednesday 23rd May, some of the Friends will be giving us a presentation on their work - including some of their most recent discoveries - and on the history of the tunnels. They will also explain how you can visit this underground curiosity on our doorstep.
