The village is situated near Beacon Hill, on the road from Monmouth to Chepstow, and has a mineral spring. The parish contains the chapelry of Trelleck Grange, and is so called from a group of monoliths near the village, supposed to be the remains of some Druidical monument.
In a garden close by is a tumulus 450 feet in circumference, said to be the spot where the earls of Clare had a castle, but is more probably a barrow raised over the bodies of the Britons slain here by Harold, as recorded on the pedestal of an ancient sundial near the churchyard gate.
