Digging from the Air
First transmitted in 1979. In the early mornings and late afternoons, when the shadows are long, Britain's ancient past reveals itself. Prehistoric, Roman and medieval markings are like ghosts from the past that only become clear when viewed from above. They are testimony to Britain's ever-changing landscape and rich heritage.This programme investigates the use of aerial photography to survey archaeological sites across Britain. The technique has helped to reveal important details relating to Britain's ancient past.
