St Johns is more or less half way between Throapham and Laughton en le Morthen on a quiet country road. It's used infrequently these days, and the only burials are in existing family plots. The earliest readable headstones are from the 1700s.
What to do with disused churches is a major headache for the CofE and the heritage industry, but they can surely not be demolished due to their historical value, yet and domestic or commercial conversion would place itself in the middle of a 300 year old gravayard!
Many such churches are in need of essential restoration and maintenance, and if you feel that you would like to contribute in some way then visit the Historic Churches Preservation Trust (HCPT), a charity founded in 1953, and the leading body dedicated to preserving Britain's ancient churches.
