 The building also houses two 13th-century effigies, thought to be those of a later Lord Robert of Ewyas and his half-brother Roger de Clifford (d.1286), and carved stone roof bosses.The abbey was run with the aid of seventeen granges, nine in the Golden Valley, four in northern Gwent, and three far to the west in Brycheiniog, centred on the parish of Gwenddwr; these last were at the extreme limit of the distance granges were supposed to be, a day's journey from the abbey.The abbey also owned property in Hereford and elsewhere, and drew revenues from five appropriated parishes.
