The idea of a sprawling network of tunnels under the streets of Wrexham is one that has long captured the imagination of its residents.
Despite evidence to suggest that such underground passages exist, the size of the hidden walkways, and whether they all interlink, draws the biggest mystery.
According to legend, the tunnels begin somewhere underneath St Giles Church, and generally end in pubs around the area.
One theory suggests centuries ago the tunnels were used to hide priests who were being persecuted by the state for their faith.
The hidden walkways were said to connect a former priory to Priory Street and Abbot Street, that are still here today.
However, despite hundreds of stories emerging from locals and historians over the years, no official documents to back up the tunnel network exist.
But one man who claims he found an entranceway to one of the tunnels underneath the streets is Nigel Jones, 66, from Wrexham.
The former joiner who has worked for Wrexham Council for four decades, told North Wales Live how he discovered a large arched door under the Butcher's Market in the 80s, while re-laying flooring in one of the market's shops.
"My role at the time was to do the repairs on the market area, so I was doing some floor repair work in the first shop as you walk in to the market on your left," he said.
"I was taking up the floors when I found an eight foot void below the floor.
"I got my ladder down and I found a large arched door, with studs, in the wall. It was left slightly ajar so I pulled it open and to the right and left to me were these tunnels.
"I was only able to go so far - I must have only gone about 10ft inside- because it was so dark. You couldn't see in front of you, or behind you.
"It was quite scary really.
"I have told a few people about it over the years, but it always seems to fall on deaf ears."
Mr Jones, who still works for Wrexham Council, now wants other people to know about his "spooky" experience as he claims he's the only person left alive who knows about it.
"All the lads I was working with at the time have now died, so I'm the only person left who knows about it. Nobody will have been down there again since I put that floor in about 40 years ago.
"I passed through there a few weeks ago now and the shop is empty. I would love to go and revisit it again."
However, Wrexham Council say it is likely it was "one of the basements" Mr Jones discovered at the time, "rather than the fabled tunnels".
One of the most well known entranceway's leading to an underground tunnel is a trap door at the front of the High Street's Golden Lion pub, which locals say runs from the Parish Church and the Royal Oak pub across the road.
A former landlord of the Golden Lion, Colin Simpson, who commented on an article written by North Wales Live in 2017, said when he ran the pub some years ago, he discovered the trap door lead to "three lanes of tunnels".
He told how he understood one ran to the Parish Church and another to the The Long Pull Pub on Chester Street and onwards towards the Royal Welch Fusiliers.
"The other, I don't know where that one led to, but you couldn't explore for all the slurry on the floor of the tunnels," he added.
Locals also point to other locations, where tunnels are said to run underneath the Butcher's Market in the town centre, under the Ijazz Indian restaurant near the Yale College and Charles Street connecting to the Long Pull pub.
Mr Jones also told how a row of terraced houses opposite St Giles - known as Temple Row - allegedly have entrances in their cellars to underground walkways leading to the church.
Under the shops on High Street - around the corner from St Giles - underground cellars with archways still exist today however, they are now blocked off.
A spokesman for Wrexham Council, said: "There are basement areas beneath many of the buildings on High Street – including the Butchers Market – and it was likely that it was one of the basements accessed by Mr Jones during work in the 1980s, given the location stated, rather than the fabled tunnels.
"There may be further linked tunnels in the town centre beyond just the basements, but this could only be investigated through disruptive and intensive work or excavation."
Anne Owen, administrator at St Giles' Church told North Wales Live that the tunnels remain a "persistent myth" and no such evidence is available at the church to suggest a connection to any of the alleged tunnels around the town.
An FOI request submitted to Wrexham Council by a member of the public in 2014 asked for information including exact locations and entrances to and from the tunnels. However, the council replied it does not hold the information requested.
