Description: The Thornborough Henges is an unusual ancient monument complex that includes the three aligned henges that give the site its name. The complex is located near the village of Thornborough, close to the town of Masham in North Yorkshire, England. The complex includes many large ancient structures including a cursus, henges, burial grounds and settlements. They are thought to have been part of a Neolithic and Bronze Age 'ritual landscape' comparable with Salisbury Plain and date from between 3500 and 2500 BC. This monument complex has been called 'The Stonehenge of the North' and has been described by English Heritage as the most important ancient site between Stonehenge and the Orkneys.
