Garreg Lwyd Enclosure 600m SE of Crosslane Cottages

Cadw's description

Summary description and reason for designation

The following provides a general description of the Scheduled Ancient Monument.

The monument comprises the remains of a defended promontory enclosure, which probably dates to the Iron Age period (c. 800 BC - AD 74, the Roman conquest of Wales) and which is located on a west-facing spur formed from a natural rock crag which has wide views on three sides. The enclosure is a sub-circular area of approximately 0.4ha defended to the west and north by the natural steep slopes with bare rock scarps, and to the east and south by bivallate ramparts which consist of an inner bank 1m high internally, 2-3m high externally; a ditch, and an outer bank 1-1.5m high externally. The ditches are best preserved on the east side. The entrance is probably on the southwest.

The monument is of national importance for its potential to enhance our knowledge of later prehistoric defensive organisation and settlement. The site forms an important element within the wider later prehistoric context and within the surrounding landscape. The site is well preserved and retains considerable archaeological potential. There is a strong probability of the presence of evidence relating to chronology, building techniques and functional detail.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
