The Wye Valley village of Trellech, South Wales is located about 20 miles west of Ross-on-Wye, close to Tintern and derives its name from the three standing stones known as Harold's Stones - 'tre or tri' meaning three and 'lech' meaning Stone. The stones date back 3,500 years to the Bronze Age and are of conglomerate rock called 'Pudding Stone'. They were dragged to the site on logs and levered into position either for seasonal information or for use at religious ceremonies. The Virtuous Well was once known as 'St. Ann's Well' and was famous for its cures. It is said to be four springs, three containing iron and each curing a different illness. Its niches held cups and offerings and there were stone seats for travellers. Tump Turret dates back to Norman times and was also possibly the site of a castle, erected during the reign of Henry 1.
