La barge aux congres (la Tantine)

Almost nothing is known about this barge: when it sank, why it sank... It is located 500 m from the island of Bagaud (Port-Cros) on a 48-metre seabed.
Some people assume that it was a tugboat equipped with a crane at the stern, and that it sank in heavy weather.

It's a difficult dive, both because it's deep and because there's often a strong current at the site. Its small size makes it difficult to locate.
