THE summer drought has unearthed a treasure trove of finds for historians taking a birds eye view of Wales. Heatwave conditions, which have parched the Welsh countryside, proved ideal for aerial archaeologists. Last night they were described as the best for at least adecade with a host of buried sites revealed from the air. The Royal Commission on the Ancient and Historical Monuments of Wales made major discoveries using light aircraft to survey the Welsh landscape. "It has been absolutely astounding. Discoveries have been made across Wales visible both as cropmarks in ripening crops and scorched grassland," said a spokesman. They include two early Neolithic causewayed enclosures, built in Wales 6,000 years ago, of which only three were previously known. |
