Chadwick End, possible former chapel. Another view. ca. SP 207 730. Both © John Bowdler (2011). John thinks that a former chapel marked on old maps is this building. There is another nearby on Netherwood Lane (the Netherwood Lane Free Church), but there was no obvious evidence that the building survives. Can you provide more information about either?
