• By the turn of the 19th century - The Royal Mint's facilities occupied almost the entire outer ward of the Tower
• 1810 - Last coins were struck at the Tower as the Royal Mint was relocated to Little Tower Hill
• 1968 - The Royal Mint moved to Llantrisant, South Wales
William Foxley – Sleeper in the Mint
A curious incident is recounted in the records of the Royal Mint from 1546.
William Foxley, a maker of melting pots, was discovered asleep at his post and remained asleep for fourteen days. All attempts to wake him failed. Even pricking him with needles and inflicting small burns did not cause him to stir.
Word of the spectacle became so widespread that even Henry VIII went to examine him personally, but he too could offer no explanation. When Foxley finally awoke, it seemed to him as if he had slept only one night. He appeared to have suffered no ill effects from the incident and is recorded in the Chapel Register as having died forty years later.
