The UK's Royal Commission on the Ancient and Historical Monuments of Wales has published some recent aerial shots of cropmarks, ancient ruins now covered by farm fields. Unusually dry weather conditions have created a golden opportunity to see these sites from the air.

The unprecedented spell of hot, dry weather across Wales has provided perfect conditions for archaeological aerial photography. As the drought has persisted across Wales, scores of long-buried archaeological sites have been revealed once again as 'cropmarks', or patterns of growth in ripening crops and parched grasslands. The Royal Commission's aerial investigator Dr Toby Driver has been busy in the skies across mid and south Wales over the last week documenting known sites in the dry conditions, but also discovering hitherto lost monuments. With the drought expected to last at least another two weeks Toby will be surveying right across north and south Wales in a light aircraft to permanently record these discoveries for the National Monuments Record of Wales, before thunderstorms and rain wash away the markings until the next dry summer.
Coflein also maintains a database of Welsh sites.
