Subterranean Secrets: Liverpool's Mysterious Williamson Tunnels

Beneath the streets of Liverpool, an enigmatic network of 200-year-old tunnels stretches for miles. Built by eccentric tobacco merchant Joseph Williamson, there are theories that the tunnels were created as an employment project, for smuggling routes, or even as the hideout of an apocalyptic cult. However, their true purpose—or even a fully-mapped understanding of where they lead—are still unknown.
