North Yorkshire, England
This well known "ghost" photo was snapped by Reverend K. F. Lord at Newby Church in North Yorkshire, England in the 1960's. He claims he was merely taking a photo of the alter and didn't see anything unusual at the time, until the photograph was developed. This particular photo has been the subject of many arguments and much controversy over the years due to the rather "fake" appearance of the figure in the photo.
The apparition picture appears to be a monk with hands folded in prayer and a ghastly face. The monk looks to be older than the building, from the time when monks were a common sight in England. Thus, it is likely the monk would date to before the time of Henry VIII, who closed down all monasteries.
