Hidden Histories, episode one
Royal Commission investigator Richard Suggett goes to investigate the ancient gates at Hay Castle with colleagues from the Oxford Dendrochronology Laboratory to find out whether it might be one of the oldest surviving gates in Europe.
The left hand gate was successfully dated to between 1610 and 1640.
The gates of Hay Castle
Surviving gates from the Middle Ages are extremely rare. The gates at Hay Castle can easily be overlooked as they are in a long-closed gateway at the rear.
The castle was rebuilt as a house in the seventeenth century and is now part of the longest-established bookshop in the town of books.
