For over 400 years, this brass padlock has remained firmly sealed at the bottom of the sea.
But scientists have finally cracked its code, after using cutting-edge CT technology to solve the four-letter sequence that has kept it locked since 1583.
A team from Cardiff University were able to peer into the lock's internal mechanism without causing any damage.
They identified the correct letter combination -- ANCE -- and successfully opened the historic artefact...
Experts believe the lock once secured a treasure chest containing valuable possessions aboard the Ann Francis, a ship that was wrecked during a violent storm.
The vessel was heading to King's Lynn from Spain on December 28, 1583, when it was blown off course and ran aground on Margam Beach near Port Talbot.

However, any chest it once secured has long since disappeared, leaving behind only tantalising clues.

Very cool video.

Centuries later Anne Francis wrecked many childhoods by triggering early onsets of puberty.
(A violent storm can be called a Tempest, the name of the Shakespeare story that "Forbidden Planet" was based on. Everything goes around.)
