According to Wikipedia:-
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.
While waiting for my sister in law’s graduation ceremony to end, my wife, CY and I visited the tunnels. We walked there and found that the place is located in the middle of some residential buildings.
There is a small exhibition hall at the entrance to the tunnel.
There are loads of artifacts dating to the 1800s such as China, bottles, jars and even an abandoned toy car were found. They are put on display. Some of these jars have engraved labels describing the products such as cream and marmite and trade marks of old traders such as W.P.Hartley (jam makers – still in existence today!), Patey & Co (purveyors of perfumes & cold Creams) and JW Lloyd Dentist.
The reason why Mr Williamson built the tunnel is unknown. But it is said that he wanted to give jobs to local men especially men who had just returned from the Napoleon War. The construction of the tunnels stopped upon the death of Mr. Williamson.
We took a tour of the tunnels. We had to wear helmets for our safety. The tunnels were damp and cold but nevertheless interesting. The excavation is currently done by volunteers in the weekends.
This connects to a cellar of a house above.
According to our tour guide, this pillar was a result of an attempt to build a foundation for a hostel located above ground. They did not know that there is a tunnel below hence they filled it up with cement.
We were told that the excavations are still on going as many parts of the tunnels remain undiscovered. If we come back in 4 to 5 more years, there will be more to explore!
Unfortunately, the tour is rather short (about 40 minutes) but our tour guide was very informative. I was hoping that we get to see the deeper parts of the tunnel. Nevertheless, I got to see the tunnels after admiring it from the Internet!
