The old Gaol is on the right of this drawing.
This particular set of gibbet irons were erected down Ralphs Lane.
The story of the last man "hanged in chains" in the neighbourhood of Boston is as follows:-
Smith was taken to Lincoln, tried, sentenced to death and hanged. The body was then taken to Wyberton to be "hanged in chains" as a warning to others. The news quickly spread that the body was on the gibbet and the place became very lively, especially on Sundays, when it was more like a Fair.
An old resident of Boston named Polly Searby, who died in the 1860s/70s used the bone of the first finger of Smith's right hand as a tobacco stopper!
When the gibbet was removed it was stored in Boston Gaol, and when that building was pulled down, the chains were on view at Mr. Ball's museum at The Whale pub (Main Ridge).
