“The Williamson Tunnels are a labyrinth of tunnels in the Edge Hill area of Liverpool, England, which were built under the direction of the eccentric businessman Joseph Williamson between the early 19th century and 1840.”

“[He]… acquired an area of land… which was then a largely undeveloped outcrop of sandstone… [and] started to build houses on the site. These houses were eccentric in design “of the strangest description” without any rational plans…”

“He continued to employ his workmen, sometimes to carry out apparently pointless tasks, such as moving rubble from one place to another, then back again. His major project was to build a labyrinth of brick-arched tunnels in various directions and over various lengths within the sandstone.”

“Williamson was secretive about his motives. This has led to speculation that he was a member of an extremist religious sect fearing that the end of the world was near and that the tunnels were built to provide refuge for himself and his friends.”

“East Grinstead has an unusually diverse range of religious and spiritual organisations for a town of its size.”

I wonder why…
