Keenley is to the west of Allentown.
I was unable to find a Primitive Methodist chapel on old Ordnance Survey maps of the area. Thanks to Philip Thornborow for finding the chapel at the junction where Appletree Bank intersects with Common Bank. To the north of the junction was Keenleywell House. To the south-west was the chapel and to the south-east a school. Street View shows the school is still standing, Keenleywell House is a copse with one or two buildings, but the chapel has gone without a trace. The map is available on the National Library of Scotland site at: – go to https://maps.nls.uk/view/132280133
As Philip comments, a typical rural Methodist chapel then – in the middle of nowhere, built for a population who have long left the land.
