The farm of Ty'n-Llwyn is surrounded by a rough circle or oval setting of 6 standing stones and two mounds. The setting encloses a considerable area of approximately 750m diameter. The discovery of an interrupted ditch enclosure or plough-levelled barrow (NPRN 403377) during RCAHMW aerial reconnaissance in 2005, with a (then unrecorded) standing stone on its summit, gave context to the stone; it seemed as likely to be a prehistoric ritual monument as a modern boundary stone.

A prehistoric date for the remaining stones in this 'setting' would be highly unusual given its size. However, their ascription to being modern boundary stones does not explain the occurrence of a mound and a complex barrow within the setting.
