The Early Development Of Irish Society: The Evidence Of Aerial Photography

The technique of aerial photography, widely recognized as of immense value to field archaeologists, had been little used in Ireland, although the relatively slight disturbance of land by modern ploughing or industrial development makes Ireland a particularly suitable region for the identification of ancient features by this method. The results of the surveys carried out by the Cambridge Committee for Aerial Photography between 1963 and 1968 are nevertheless surprising. Many ancient earthworks have been revealed by differences in soil-colour or crop-growth, and the natural and man-made environments of these and other prehistoric and early Christian settlements can be fully appreciated. The pattern of settlement emerges over a wide area, as does the character of large and complex sites such as Tara, while detailed oblique views pick out smaller structures invisible on the ground.
