Harolds Stones

Harold's Stones

Copyright: Paul Blades. Original available at Megalithic Portal.

A probable single stone row measuring 13.7m long, including three large upright orthostats situated within a valley with a restricted viewshed. The row is orientated north east to south west and stands within a medieval township and later field system. The central stone has a pair of cup-marks on one face. There are no other broadly contemporary monuments within the vicinity although the stones are depicted on a nearby sundial erected in 1689.

Category: Probable.  The adjacent historic earthworks provide an historic rather than a prehistoric context for this monument and it is possible that this is the structural remains of a once substantial building. Short stone rows formed by three substantial orthostats are not a characteristic of Welsh rows and it has been suggested that this may be the remants of a chambered tomb.  On balance a stone row interpretation seems most likely, supported by the village being named after the stones (which suggests considerable antiquity) and one of the stones having a pair of cup-marks, but enough uncertainty exists to preclude a more definite identification.


This stone row is of Type S2. Information on this form of stone row and other rows of this type is available here.


The three stones stand in the corner of an historic field. View from north west (Scale 1m).

Detail from the sundial in the nearby church showing the three standing stones. This stone depicts other antiquities in the area and was carved for Lady Magdalen Probert in 1689. 

The sundial now stands near to the church entrance.
