This site lies at a height of 1,580 feet (c.481 m) on a small rounded summit of the Central Welsh Plateau in Powys, about 7½ miles (c.12 km) west of Tefeglwys and about ½-mile (c.0.8 km) south-west of Dylife. An enclosure measuring 82 feet by 73 feet (c.25 x 22.5 m) and covering an area of only 0.13 acre (c.0.05 ha), was defined by a turf rampart and a single ditch with a gateway 10 feet (c.3 m) wide in the centre of the north side, facing the road. This is most likely a Roman fortlet or signal-station set beside a main east-west route (Margary #64, now called Glyndwr's Way), similar to others in Wales at Hirfynnydd and Pant-teg Uchaf.
