Possible Neolithic and Bronze Age megaliths west of Exmoor
Coloured dots are standing-stone records (confidence). Pale diamonds are 1830s tithe field-names — Longstone, Greystone, Hoarstone and the like. Those names may mark a prehistoric stone, a medieval bond-stone, or only a name; they are a separate layer, not dated monuments. West Middleton is scheduled as post-medieval staddle stones, not a prehistoric row.
The list was drawn in 2026 from Historic England scheduled-monument open data, the Devon Historic Environment Record, National Trust heritage records for Morte and Lundy, Palmer’s 1937 Ilfracombe survey as cited on the HER, Chanter and Worth on Mattocks Down, and nineteenth-century tithe field-names. It covers North Devon and Torridge west of Exmoor, including Lundy. Dartmoor and the Exmoor miniliths are excluded. Grades keep scheduled or accepted megaliths apart from possible, doubtful, lost, folklore and rejected stones.
The diamond overlay is the tithe-name layer: plot names from the 1830s apportionments (Long Stone, Grey Stone, Hoarstone, White Stone, Broad Stone, Great Stone, Quoit). A name is not a date. Some will be prehistoric standing stones; many will be medieval markers or later agricultural stones. Field-precision pins are used where a grid is known; otherwise the name is shown at the parish centre.
