Series of 19th century subterranean excavations in Liverpool, England

The Williamson Tunnels are a series of extensive subterranean excavations in the Edge Hill area of Liverpool, England. They are thought to have been created under the direction of tobacco merchant, landowner and philanthropist Joseph Williamson between 1810 and 1840. Although popularly described as "tunnels", the majority comprise brick or stone vaulting over excavations in the underlying sandstone. The purpose of the works remains unclear and remains a subject of heavy speculation; suggestions include commercial quarrying, a philanthropic desire to provide employment, and Williamson's own eccentric interests. After being gradually infilled with rubble and spoil during the late 19th and early 20th centuries, they remained largely inaccessible until archaeological investigations were carried out in 1995. Since then volunteers have rediscovered and excavated an extensive network of tunnels, chambers and voids across several sites, with sections open to the public. Guided tours are available at the Williamson Tunnels Heritage Centre and the Friends of Williamson's Tunnels, and volunteers continue to uncover new sections.

In 1805, wealthy businessman Joseph Williamson acquired an area of land in Mason Street, Edge Hill, Liverpool, which was then a largely undeveloped outcrop of sandstone with a scattering of scars from small scale quarrying. The land was held under a lease from the West Derby Waste Commissioners, who retained rights to the minerals under it: Williamson started to build houses on the site, which then adjoined growing and fashionable areas of Liverpool. According to the account of a 19th century Liverpool antiquarian, James Stonehouse, these houses were eccentric in design and "of the strangest description" without any rational plans. The ground behind them dropped sharply, and in order to provide large gardens Williamson built arched terraces over which the gardens could be extended. He continued to erect and alter many further buildings on the site during the period, including a large house in Mason Street occupied by himself and his wife. To carry out the work he recruited a large pool of labour from among the poor and needy of the area, including soldiers left unemployed at the end of the Napoleonic War; according to Stonehouse, he occasionally engaged them to carry out apparently pointless tasks, such as moving rubble from one place to another, then back again. Over the same period, his workers also excavated a series of brick arched tunnels and vaults at various depths within the sandstone. They covered a wide area, extending to the boundaries of Williamson's lease and possibly beyond. Stonehouse, who traversed parts of the tunnels in 1845, described the excavations as a labyrinth of "vaulted passages [ ] pits deep, and yawning chasms", including a "fearful opening" beneath Grinfield Street with two "complete four roomed houses" in the side of it connected by a spiral passage. This apparent tunnel building activity continued until Williamson's death in 1840. In August 1867 the Liverpool Porcupine described the tunnels as being "a great nuisance" because drains ran straight into them, in one place creating a cess pool full of offensive water 15 feet (5 m) deep, and they were being used for dumping refuse, including down chutes built into the buildings above for the purpose. In the later 19th century the Corporation of Liverpool began backfilling the tunnels with rubble and other waste from building demolition, a process that continued sporadically into the 20th century. Little information about the excavations had been recorded and nearly all knowledge of them, and of Williamson's life in general, was derived from the 1845 account of James Stonehouse. Although not published at the time it was written, it was referenced in Stonehouse's later works and was finally reprinted in full by Charles Hand as part of a 1916 article, "Joseph Williamson, the King of Edge Hill", published in the Transactions of the Lancashire and Cheshire Historical Society. Hand's work saw a brief revival of interest in Williamson and his life.

In 1881, the North Staffordshire Institute of Mining and Mechanical Engineers conducted a field trip to Liverpool during which they surveyed some of the surviving excavations, producing a plan and dog leg section of the main parts of the site. In the early 20th century, soldiers from the 1st Lancashire Engineers and the West Lancashire Territorial Forces Association, whose drill hall in Mason Street stood on top of one of the tunnels, carried out additional surveys. The Association produced a map of the excavations although, as many were filled with rubble, this had to be left incomplete. The map also showed the course of the London and North Western Railway cutting between Edge Hill and Lime Street stations which ran through the area. Public interest in the tunnels waned through much of the 20th century and many of the sites were further buried or destroyed by new construction. However, from the 1980s onwards interest in Williamson steadily increased, leading to the formation of the two major societies and, eventually, excavation of tunnels across several sites. In 1995 a geology student from Liverpool University carried out a micro gravity survey of the site. Some of his findings were ambiguous, perhaps due to rubble infill, and not all of them seemed to correspond with those of the Forces Association's 1907 map. Later that year a professional firm, Parkman, carried out a survey on behalf of the Joseph Williamson Society. Both societies eventually acquired the rights to begin digging, and over time a considerable portion of Williamson's legacy has been rediscovered and cleared of the last two centuries' accumulated spoil and rubble. In the course of excavation, a substantial number of artefacts have been found – some dating back as far as the 1830s – including bottles, plates and other crockery, pipes, vintage signs, military items and other items, much of which was probably refuse dumped in the tunnels. Many of these finds have been cleaned and put on display.

The purpose of the excavations has been the subject of widespread speculation. According to Stonehouse's near contemporary account, Williamson was secretive about his motives, leading to a great deal of speculative local folklore. Upon hearing that Stonehouse planned to publish his research on Williamson's excavations, Williamson's friend, the artist Cornelius Henderson, threatened to sue Stonehouse both for libel and trespass, leading to the paper's suppression for some years. The most commonly related explanation is that they were a philanthropic endeavour. Williamson's own explanation was reputed to be that his motive was "the employment of the poor"; his workers "all received a weekly wage and were thus enabled to enjoy the blessing of charity without the attendant curse of stifled self respect". Certain features of the tunnels appear to support this theory; there are many architectural features that seem unnecessarily decorative, hidden deep below the ground in chambers that would likely have been dimly lit and rarely seen. By way of example, at the Mason Street site a beautifully constructed stone arch was recently uncovered in an otherwise plainly constructed side chamber, deep underground, with no obvious explanation for its purpose. These features could be interpreted as Williamson helping his employees improve their skills. Another suggestion, 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 him and his friends, originated in recent times with a casual suggestion made on a television programme. No evidence has been found to support the existence of such a sect or that Williamson, a practising member of the Church of England, belonged to one. Many of Williamson's workers were said to have later found employment in railway construction with the skills they had learned. More recent research by academics at Edge Hill University has concluded that the 'tunnels' were in fact the result of work by Williamson to restore ground levels after quarrying. Most of the excavations are directly within a band of high quality sandstone and show clear signs of having been carried out using established quarrying techniques designed to produce single large pieces of stone suitable for building use. In addition, the cross sections of the works produced by the 1881 survey reveal a typical stone quarry profile. It seems possible that his secrecy was at least partly driven by a need to conceal his avoidance of both large amounts of income tax and mineral rights duties due to the West Derby Waste Commission from the sale of sandstone.

The Joseph Williamson Society was founded in 1989. It was incorporated as a private limited company in 1996 and acquired charitable status in 1997. Its aim is to promote interest in the life and philanthropic achievements of Joseph Williamson and takes the form of talks, tours, publications and educational visits. In autumn 2002, after much excavation, removal of rubble and renovation, one of the three sections of the site, the Stable Yard section, was opened to the public as the Williamson Tunnels Heritage Centre under the trusteeship of the Joseph Williamson Society. Visitors are taken on a guided tour which includes the south tunnel and the double tunnel and various artefacts are on view including some of the items which have been uncovered in the excavations. A programme of events and entertainments is organised on the site. The entry to the heritage centre was formerly part of the Lord Mayor's Stable Yard which closed in 1993. The stable was again home for a horse for a while in the early 2000’s when Pop took residence in 2003.

The Heritage Centre allows visitors to see a substantial section of the tunnels, including the impressive "Double Tunnel". They are open Tuesday Sunday during the summer months (Thursday Sunday in Winter) with no advance booking required. The centre is also used as a unique venue for live music and events, as well as being available for use as location for filming and training.

The Friends of Williamson's Tunnels (FoWT) is a registered charity, managed by a board of trustees and committed to exploring, excavating and preserving the tunnels, with the work of excavation carried out by volunteers. FoWT's main base on Mason Street is the site of Joseph Williamson's house, largely demolished except for a small section of the facade which remains standing. However, excavations there have uncovered an extensive portion of the site below ground level, as well as numerous tunnels branching off in various directions at different depths. Beneath the basement area is a large chamber known as the "Banqueting Hall", which gained its nickname from oft repeated stories of Williamson holding lavish banquets for his most loyal friends, though it is highly unlikely the space was ever used for this purpose. As of 2019 the "Banqueting Hall" has been completely cleared of spoil, but excavations continue in newly discovered tunnels leading off from the main chamber. A second section of tunnels is accessed from the "Paddington" site, comprising a series of underground galleries on several levels, leading to a large vaulted chamber approximately 40 feet (12 m) high from floor to ceiling. The floor of this chamber is approximately 60 feet (18 m) below ground level and was cleared in 2016 after several years of excavation. The sites have been used as a filming location, and have appeared in several documentaries featuring the tunnels and FoWT volunteers. The group has been featured in several news items, including domestic TV channels like the BBC and ITV.

The general public can visit the "Paddington" site with free guided tours on Wednesdays and Sundays, while the Mason Street site can be accessed by FoWT members. Members can also go to regular historical talks and other events.

In Series 13 of Doctor Who, entitled Doctor Who: Flux, the Williamson Tunnels, as well as Joseph Williamson and James Stonehouse, are featured. In the story, with digging set in the 1820s, Williamson seems to be aware of "the cataclysmic, the impossible" lying ahead, which in 2021 prove to be the unknown force the Flux, tearing through the universe, reducing everything it touches to nothing. Williamson appears several times throughout the series, appearing in locations and time periods he couldn't have naturally reached; the penultimate episode reveals that the tunnels somehow contain portals across time and space, which Williamson has been exploring in an attempt to find a way to stop the Flux. Joseph Williamson's life and the building of the Williamson tunnels have been dramatised by Liverpool based playwright and screenwriter Karen Brown in her stage and radio play The King of Edge Hill. An examination of the point at which philanthropy turns to obsession, the radio version of the play was broadcast on Radio 4 on March 21, 2000 to considerable acclaim. The stage version played at Liverpool's Unity Theatre in 2007, and won the HSBC award for New Playwriting Talent’ and ‘The Echo Arts award for best New Play.
