Felin Fach was located on the north-east (right) bank of the Afon Drowy, 2.4km east-north-east of Llanarth. A leat 350 metres long conveyed water to a mill pond in the angle of the lane (a site now occupied by a modern bungalow) immediately north-east of the mill building. Both the 1st and 2nd editions of the historic 25-inch O. S. maps, published in 1890 and 1905 respectively, annotate Felin Fach as a working corn mill. The building has been demolished, and a brick-built bungalow now occupies the site.
