This week, we’re tracing the story of a historic heist. But it’s not the one from the 1660s involving the Crown Jewels and the Tower of London that some people might recognise.

This raid dates back more than 700 years to 1303 and the reign of King Edward I, taking place in unlikely surroundings. Helping us piece together the story are English Heritage’s head properties curator Dr Jeremy Ashbee and medieval historian Sally Dixon-Smith.
