Gray Hill, Monmouthshire

Gray Hill (Welsh: Mynydd Llwyd) is a hill approximately 2 miles north of the village of Llanvair Discoed, Monmouthshire, South Wales, rising to 896 feet (273 m) above sea level.

The summit of the hill has views over the Caldicot Levels and Severn estuary, as well as inland.

Geologically the hill forms a detached part of a longer north and west-facing sandstone scarp which runs roughly northeast through Monmouthshire from Llandevaud to the Wye valley south of Monmouth.

[1] Gray Hill is known locally for its prehistoric remains which include standing stones, a stone circle at a height of about 900 feet above sea level and overlooking the Severn Estuary, as well as cairns, field boundaries and enclosures including a D-shaped Neolithic or Bronze Age enclosure.

The stone circle is approximately 32 feet in diameter and has been dated to the Bronze Age, circa 4000 years ago.
