Williamson Tunnels Virtual Tour The Williamson Tunnels under Edge Hill, Liverpool have been described as "the largest underground folly in Britain". Joseph Williamson made a fortune in the tobacco trade, before retiring in the early 1800s to Edge Hill and spending almost all his considerable fortune paying men to build an immense and intricate labyrinth in the soft sandstone hillside. According to historical writings, he built the tunnel system simply to give unemployed men "an honest day's work". This short film is an excerpt from 'Williamson Tunnels Virtual Tour' - a DVD about the mysterious tunnels under Edge Hill which is available to buy for £8 from www.williamsontunnels.com
