First Ordnance Survey map of Lesmahagow
The first Ordnance Survey 6″ to 1 mile map of the Lesmahagow area shows a major change in map making. By 1864, the detail included in the maps is considerable.
The map shows the Monastic Lade or water channel running into the Nethan near Turfholm Bridge. St. Foxes Castle is a puzzling earthwork whose setting was disturbed by the railway coming into Lesmahagow.
