Blaen Cwm Bach farm is an unlisted farm house situated within the site of the Blaen Cwm Bach Roman Camp. There was a large temporary marching camp based here which has been attributed to the campaigns of Sextus Julius Frontinus sometime during the period AD73 to 78, along with two other large camps at Twyn-y-Briddallt and Pen-y-Coedcae.
