Hello Carole
Nice to have you on board. Regarding the “Talbot Hotel” . During my studies of Old Wolverhampton over the years I have discovered there have been many hostelries in various parts of the town were “Ladies of the Night” have plied their trade, and perhaps “Talbot Hotel” was no exception at some time. considering the age of the original House.
But I doubt if the Gents would have needed a tunnel especially dug for that popular pastime as the original entrance was opposite what became the Old Still in King Street, for many years.
I think you may have opened a can of worms here Carole
Below the old cellar head.
