More than 450 years ago, a three-masted ship sank in a hurricane off the coast of Florida, taking with it France’s hopes of colonizing the peninsula.Among the objects identified underwater are three bronze cannons decorated with a traditional French fleur-de-lis symbol, as well as a prized marble column bearing the coat of arms of the Kingdom of France, which Ribault was supposed to install on land to mark French sovereignty.As a last resort, GME argued that France had benefited unduly from the US company’s work to locate, photograph and search the wreck.
