A probable disc barrow, listed by Grinsell as Winterborne St Martin 3 (in his list of bowl barrows) and by RCHME as Winterborne St Martin 111. Part of a barrow cemetery (see SY 69 SW 49 and associated monuments), in 1981 the Ordnance Survey recorded it as a mound 14 metres in diameter and circa 0.5 metres high, surrounded by an outer bank enclosing an area 30 metres in diameter (measured from the top of the bank) The bank was only visible as an earthwork on the south and east sides only. RCHME had previously noted a ring ditch surrounding the mound visible on air photographs as a cropmark circa 80 feet in diameter. This barrow was originally recorded as part of SY 69 SW 49. That record should be consulted for additional sources and information.
