Maen Ceti is a dolmen dating back to the Neolithic era located in Wales. The site is located out in a field next to two other Neolithic cairns. The dolmen consists of about 10 small support stones and one large capstone. A part of the capstone has been broken off and now lies on the ground next to the dolmen. Stones that once formed a cairn around the burial chamber are also visible around the dolmen.
