Joseph Williamson’s Tunnels

MYS424: A Liverpool merchant spent thirty years having his men tunnel beneath his own neighborhood — and never once explained why. By his death in 1840, Joseph Williamson had honeycombed a hillside in Edge Hill with brick-vaulted passages, chambers three stories underground, and spaces large enough to echo a voice seven times. His neighbors called him the Mole of Edge Hill. No one has fully solved why he did it.

Jimmy Akin and Dom Bettinelli investigate the Williamson Tunnels of Liverpool — who Williamson was, what early visitors found underground, and seven competing theories for why he built them.

Williamson made his fortune in the tobacco trade, married into his employer’s family in 1802, and retired in 1818. He was wealthy — his estate was valued at £40,000 at his death — but he dressed in patched corduroys, answered tax inspectors with jokes about church towers, and tested his friends by serving beans and bacon before revealing a feast upstairs for those who stayed. He paid pew rent at St. Thomas’s Church from 1816 until his death and befriended ministers from Anglican, Unitarian, and Independent congregations.

His tunnels are stranger still. Antiquarian James Stonehouse toured them in 1845 and found dungeons carved from solid rock with no light or ventilation, monstrous wine bins, and — most remarkably — two complete four-room houses cut into the bedrock and connected by a spiral staircase. Those houses have never been found in modern excavations, though volunteers believe they are still down there under nearly two centuries of rubble.

Seven theories are examined and weighed. Freemasonry and smuggling are dismissed for lack of evidence. The popular apocalyptic refuge theory — Williamson building bunkers for the end of the world — is called out as modern folklore: no period source supports it, and the staff of the Williamson Tunnels Heritage Center call it “total guff.” A 2014 geological paper proposes the tunnels are byproducts of slot quarrying: Williamson was following the best seam of New Red Sandstone for building material, quietly understating his extraction to avoid mineral rights duties. The charity theory holds that he was employing post-Napoleonic War veterans flooding Liverpool after 1815, giving them wages rather than handouts — even political opponents at the Liverpool Mercury confirmed he never refused to hire a poor man they sent his way.

Jimmy’s verdict: the strongest explanation combines quarrying and charity, with vaulted voids left behind as the tunnels. A private, deeply Christian man who did good and said nothing about it.
