The largest of the two known Roman military practice works at Rhyd Sarn measures 255 feet from south-west to north-east by 165 feet transversely (c.78 x 50 m), enclosing an area of just under 1 acre (c.0.39 ha) within a single rampart and ditch which is remarkably well-preserved on the north. The smaller work lies some 700 feet to the west.
