Padlock From 400‑Year‑Old Shipwreck Finally Decoded

A 400‑year‑old brass padlock, recovered from a beach near Port Talbot in Wales, has been decoded after two decades of mystery. The lock, part of the cargo of the Spanish‑schooner Ann Francis that sank in 1583, was found by metal‑detectorist Peter Hughes in 2017 alongside silver coins and other relics. Hughes spent 20 years attempting to open the lock, but modern technology finally solved the puzzle. Researchers at Cardiff University used a micro‑CT scanner to examine the lock’s internal mechanism, revealing that the correct combination spells “ANCE.” The padlock’s four rings each contain six movable letters, yielding 1,296 possible combinations, and the fixed letters at the ends were designed to mislead potential thieves. The decoded lock is now part of the Museum of Wales’ “Tides of Treasure” exhibit, which showcases the ship’s recovered artifacts. The breakthrough demonstrates how scientific imaging can unlock historical enigmas and preserve maritime heritage for future generations.
