Williamson Tunnels - Investigations and Archaeology

Investigations and Archaeology

In the early 20th century soldiers from the West Lancashire Territorial Forces Association explored the tunnels. Their drill hall in Mason Street stood on top of one of the tunnels. In 1907 the Association produced a map of the tunnels, which was incomplete because many of them were filled with rubble. 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 of the Williamson tunnels. In 1995 a geology student from Liverpool University carried out a micro-gravity survey of the site. Some of his findings were ambiguous because of the rubble filling the tunnels and not all of his findings corresponded with those of the Forces Association. Later that year a professional firm, Parkman, carried out a survey on behalf of the Joseph Williamson Society. Since then further investigations and excavations have been carried out.
