Joseph Williamson’s Tunnels

Joseph Williamson’s Tunnels are the maze-like remains of excavations under Edge Hill. They are the work of Joseph Williamson under the streets of east central Liverpool, constructed in the early part of the 19th Century.

Williamson had bought land on Mason Street on which to build houses. He employed a number of men to dig tunnels, build vaults and construct arches through the sandstone outcrop. Eventually the area bounded by Mason Street, Grinfield Street, Smithdown Lane and Paddington was riddled with underground excavations.

A number of theories exist as to why Williamson built these structures. The most popular explanation is that he wished to employ the local poor, rather than give handouts. Williamson himself lent support to this view, noting how poverty brought with it “the attendant curse of stifled self respect”.

The tunnels have never disappeared entirely from public consciousness, but since the early 1990s interest in the remains has grown. The Williamson Tunnels Heritage Centre presents the site to the public. The Friends of Williamson’s Tunnels carry out investigations (including excavation and survey) on the site and campaigns for its protection.

Excavations at Joseph Williamson’s Tunnels

Excavation are constantly uncovering new tunnels, which is the wonderful thing about this site. In recent years the Friends of Williamson’s Tunnels have done a lot of work at Williamson’s house on Mason Street.

The house itself is no now more than a shell. For many years it was the site of a garage, and ironically this has helped preservation. The garage owners built a concrete roof over some rooms (the parts now called the Wine Cellars). This has kept them intact, and as the Friends carry on digging, they reveal more untouched brickwork. The site at Paddington, just around the corner from Mason’s House, is also revealing amazing depths.

A tour of Williamson’s Tunnels

Occasionally I get to treat myself to a history-indulgent week on Merseyside. One where I catch up on the ever-changing town centre (it’s still changing), check that my book’s still on the shelves of Waterstone’s (it’s not 🙁 ) and book myself on a tour or two (I did). One of these weeks back in 2016 gave me a chance to catch one of the Williamson Tunnels member’s tours courtesy of the Friends of Williamson’s Tunnels (FoWT).

Despite a little mix-up on my part, which revealed the existence of two societies concerned with the Tunnels, we were well taken care of by the energetic volunteers who make up the Friends. A special thank you to Chris, who booked us in, and Jamie and Tom, who, along with Chris, were our guides for the three parts of the tour.

Jamie and Tom took us down into the wine bins first, introducing us to a section of tunnels under Joseph Williamson’s own house (or what was left of it), and giving a great overview of how new tunnels are generally discovered, and how they’ve been damaged and neglected over the years. This plot of land was a garage from the 1930s until the 1970s/80s, but luckily the garage owners were rather sparse in the concrete and steel that they inserted into the ground. Just a few I-beams here and there, and a concrete roof, meant that the tunnels were largely intact. We also learnt that film crews like to use the underground arches as evocative locations, the most recent being Poe’s The Cask of Amontillado. Those of you who know the story may be able to guess at the nature of the tunnel’s use here…

The second section of the tour, with Chris as our guide, took us down a longer ladder (with harnesses to keep us from falling too far, should we slip!) into the Gash and, eventually, the Banqueting Hall. The Gash is a tall narrow passageway that was possibly once a natural fissure in the sandstone. This fissure had been widened slightly, and the suggestion has been made by an earlier visitor that its floor may have sloped downwards in order to transport quarried sandstone blocks to the entrance of the tunnels, ready for shipment elsewhere. The Banqueting Hall is an impressive gallery, currently still with a lot of spoil and rubble in, which demonstrates the impressive construction skills of Williamson’s workforce. There are about 5 feet of ‘floor’ to be removed before the bedrock is reached.

Finally, we made our way around (now without harnesses) to the Paddington site, with a proper entrance in front of a student accommodation block. This network of tunnels was saved for last, and it would soon be easy to see why. The entrance way/lobby displayed a map of the known (and supposed) tunnels, pulled together from recent excavations, a military survey in the 19th century, and various other historical sources and rumours. There was also an archive of newspaper articles of a trip into the tunnels in 1925 by local historian Charles Hand and the Lancashire and Cheshire Historical Society. The biggest mystery is why these little forays didn’t become more popular! Still, we were about to see that the party who descended ‘for about half a mile’ into the ground were not to know the half of what was there.

Chris showed us an impressive array of finds from the constant excavations, and we watched as keen volunteers brought buckets of soil to the surface. The finds included plates, dolls’ heads, cups, coins and bottles, many in unbroken condition. For someone who’s worked on archaeological sites around the country, to hear that only 80% of finds are broken was very impressive! The star find was a King Edward mug which showed the face of the monarch expertly crafted into the base, as you can see here.

So why did Williamson built these vaults and dig these tunnels? Research and hypotheses have advanced since I was last here in the mid 2000s. There’s still some agreement that he was probably helping to give work and training to local men (not just soldiers), and this can be proven by the extremely high quality of the archways and sandstone finishes, which were much more than the job required. No one but the workers and Williamson himself was probably ever expected to see these features.

I enjoyed two of the more practical ideas, which sit easily hand-in-hand with the one above. The first, as Tom told us, was that Williamson didn’t own the mineral rights to the sandstone under his house, so he couldn’t legally extract the stone and sell it. However, he was known as a builder, and knew brickmakers in the area. It might be the case that he secretly swapped the sandstone for bricks. No transaction papers, no paper trail. He would then have all the bricks he needed to carry on his registered business, and no one would bat an eyelid.

Secondly, the area around Mason Street and Paddington was once the site of sandstone quarries even before Williamson arrived, and so the builder might merely have being reclaiming unusable land for the houses constructed atop the arches. The Tunnels and vaulting allowed him to put fashionable gardens behind his own and other houses, which would otherwise have been impossible. Despite being a builder, his own schemes were just a little whimsical and unplanned, hence the likes of the Triple Decker Tunnel and other odd-looking features.

Whether any, or all, of this is true, we may never know for certain, but it was eye-opening to hear how the Friends of the Williamson Tunnels have made both physical and historical progress in bringing the site, literally, to light.

If you want to go on one of these tours (and even if you don’t!) then I can’t recommend highly enough that you join the Friends (FoWT). It’s ridiculously cheap at £5 per year, and all your money goes into keeping this heritage safe. This is a unique site, and needs to be preserved, and as a member you get better access on these special tours than the general public. You also get a regular newsletter giving updates on their progress and other news. Get over to their website now and sign up!

Further reading on Williamson’s tunnels

Dr. David Harrison, Williamson’s Tunnels and Freemasonry, acceessed 16th October 2025. Speculates on the connections the Tunnels, or Williamson himself, may have had with Freemasonry. No concrete evidence exists, but circumstantial clues may point to at least one Mason having been in the tunnels at some point.
