The Drybridge Menhir is estimated as being over 3000 years old [needs verification]. Old maps from the early 19th century mark and name the stone; and a number of prehistoric artefacts recovered from the region (including a cursus,, several sites of flint flake deposits and a twin concentric circle structure) indicate it may have been of some ceremonial importance.
The standing stone at Stane Field (NS 359 364), Drybridge, is the only one recorded for this local authority area. It stands close to the old railway station. This standing stone is on level ground in a field of young crop at about 20 m OD. It has a maximum height of 2.6 m, and as stated, is roughly square with a girth of about 4.0 m and a maximum width of 1.3 m
