Gaerllwyd is a village in Monmouthshire, south east Wales, United Kingdom.
Gaerllwyd is located 6miles south east of Usk and 7miles north west of Chepstow on the B4235 road.
Gaerllwyd is set in a very rural agricultural area in the heart of Monmouthshire. The village has a Baptist chapel, situated on the Gaerllwyd Crossroads, which is still in regular religious use. Near the chapel is a Neolithic burial chamber, or cromlech dated to around 4,000 BC. It is made up of a capstone which would have had three upright stone supports.[1] The outer cairn has been removed by road construction and stone robbing, although archaeologists are uncertain whether a covering mound would ever have been in place.[2] To the south there are some Early Bronze Age monuments including two stone circles, a standing stone and a round barrow cemetery.[3]
