Sizeable standing stone of indeterminate age, marked on OS 1:25000 as a Boundary Stone (BS). Info from Coflein indicates that it may well be of an early date:
1. A stone, c.2.3m high, once carrying the inscription “1844”, whilst thought to have served as a boundary mark is believed to signal the site of a chambered tomb.
