This photo was taken at Woodchester Mansion in Gloucestershire, England. Woodchester Mansion was built on a previous dwelling of a Georgian country house, which was named Spring Park. It is not quite known when Woodchester Mansion was started but by 1866, both the clock tower and roof were in place.
It is said that in 1868 that the workmen downed tools and were never to return. There were rumours that a murder had taken place and there also some suspicious deaths and these are still believed to this day despite there being no real evidence. There's a lot of history to this building and the area but I'll just be focusing on the incident to which the ghost photo is related. .
