Every year on sites and fields all over Britain enthusiasts brave winter mud and summer flies to excavate and record aspects of our heritage which might otherwise be destroyed. Tonight the Prince of Wales sees the films of the work of the six amateur groups selected for this year's final and presents the Chronicle Archaeology Award for 1978 to the winner. The subjects for the films range from the discovery by a former RAF pilot of a vast series of prehistoric tribal boundaries in the East Midlands to a lecturer and his wife who spend their holidays and weekends recording ancient cider-making equipment in the West of England. Magnus Magnusson introduces the programme which will also present the winners of other awards organised by RESCUE, the British Trust for Archaeology.
