A W M Chapel is clearly marked on the OS Early Sheets at Cwm Llinau, Powys. On my visit in 2016 it was a Grey course stone building with a finer stone yellow arched window setting. A foundation Stone above the door said SOAR 1870 and another stone on the left hand side of the chapel front level with the left side front window bottom reads
THIS STONE WAS LAID BY JOHN JONES OF BILSTON AUGUST 23 1870
There was no attached graveyard.
NGR SH 8485 0789
A current Google Street view image suggests the building has been reroofed and modernised within the last two years but I am still unclear if it is still a practicing Chapel
