In the first century BC, it was not possible to sail around Cape Planck or Cape Diomedes during a major storm. This is an area of the south and bora, local winds associated with the Argonaut myth that conspire to create one of the deadliest navigable points in the east. A Roman ship carrying 150 amphorae full of wine from northern Italy to Greece anchored for the last time in the bay of Gornji Muli in Rogoznica. For a medium-sized ship overloaded with amphorae, even a closed bay was not safe. It overturned and sank to a depth of 20 meters, hitting underwater rocks, and its wreckage was scattered over a field measuring 13x10m. The site was explored and preserved in 1998. During the cold days of winter and war in January 1942, a British submarine sank a large Italian transport ship called the Nuncio between the Mulo and Velika Smokvica lighthouses. The wreck lay undiscovered at the bottom of the sea for sixty-six years. The waters around Rogoznica contain numerous shipwrecks from different historical periods, so we could say that in the deep blue sea there is a museum, a multitude of historical material that intrigues scientists and tourists.
