Well done Jack. Spot on and I hadn't even posted my photo of the house ( or what's left of it)
What gave it away?
Williamson Tunnels Edge Hill Liverpool
We had a pre arranged tour there on Sunday and it was a great experience. The charity is run by very hard working, knowledeable and enthusiastic volunteers and well worth a visit.
The Williamson Tunnels consist of a labyrinth of tunnels in the Edge Hill area of Liverpool, England, which were built under the direction of the eccentric businessman Joseph Williamson between the early 19th century and 1840. They remained derelict, filled with rubble and refuse, until archaeological investigations were carried out in 1995. Since then excavations have been carried out and part of the labyrinth of tunnels has been opened to the public as a heritage centre.
