CT scans cracked the code of a brass lock from a 1583 shipwreck off Wales, 443 years later, intact

A fascinating shipwreck dating back to 1583 was discovered off the coast of Wales, revealing a brass combination lock that had remained sealed for centuries.

Researchers utilized advanced micro-CT scanning to unveil its four-letter combination, ANCE, preserving its condition.

This lock is linked to the Ann Francis, a vessel that tragically sank during a storm while returning from Spain.
