I recently came across this old black and white photograph and have been trying to work out where it is. After studying the photograph and after a tour of local churches, I believe it is St. Mary's Church at St. Mary Hoo, which is no longer an active place of worship. Please let me know if I am wrong. The second photograph, of St. Mary's Church, was taken a few months ago and points in a similar direction to the older photograph - east of Hall Road, near to Moat Farm Road.
If my assumptions are correct about the location of the old photograph, the farmer probably worked at nearby Moat Farm. Despite being slightly obscured from view - it would be nice to know who he was!
