Code Cracked for Margam Shipwreck Padlock Solving 400-Year-Old Mystery

CT scans revealed the four-letter code on a brass padlock from the Ann Francis, which experts say was one of 1,296 possible combinations.

  • On Wednesday, researchers from Amgueddfa Cymru and Cardiff University used CT scanning to open a 400-year-old brass combination lock recovered from the Ann Francis shipwreck off the Welsh coast.
  • Metal detectorist Peter Hughes discovered the lock near Margam Beach in 1999 while searching for artifacts from the Ann Francis, which sank during a storm on 28 December 1583 while returning from Spain.
  • Dr. David Williams of Cardiff University's School of Engineering identified the secret four-letter code ANCE by creating a detailed 3D image of the lock's internal mechanism, which has 1,296 possible combinations.
  • The padlock is currently on display at the National Waterfront Museum in Swansea as part of an exhibition exploring Wales' maritime history and international connections until September 2027.
  • Senior curator Alastair Willis of Amgueddfa Cymru noted the lock remains in "excellent condition," though researchers face an enduring mystery: whether the letters ANCE held special meaning to its original owner.
