| Record Name | Grinton Earthworks |
| Record Description | Two glacial mounds approximately 300 metres to the east of Grinton Bridge beside the River Swale on the southern bank. They can be viewed in Google Earth using this Grinton Mounds link (You need to have installed Google Earth then click this link and allow Google Earth to open it.)
They have been variously described as: Iron Age Hill Fort or a Roman Siege Fort but there appears to be no hard information published on the Internet to support either suggestion. The best suggestion appears to be they may be an Iron Age / Romano-British defended settlement, however a pre WW2 excavation suggested they were medieval, but didn't exclude a prehistoric past. There is evidence of medieval settlement and rig and furrow ploughing nearby. |
| Dimensions | Western mound approximately 100x80 metres. Eastern mound approximately 150x70 metres. |
