The inscription predates the French Revolution and memorializes a man who died in western France.

A mysterious inscription engraved centuries ago on a rock at a French beach was finally unscrambled, thanks to an international competition launched in 2019.

A mysterious, 230-year-old rock inscription in a French harbor stumped translators for decades. But now, nearly a year after the launch of a contest to decipher the writing, experts have finally decoded its secret message.

In May 2019, officials in the town of Plougastel-Daoulas in Finistère, France, challenged members of the public to interpret the 20-line carved message, Live Science previously reported. Etched into a stone in a cove that's accessible only at low tide, the writing included two dates — 1786 and 1787 — as well as letters and symbols such as a heart-topped cross and a ship.
