Archaeologists diving into the Caesarea National Park harbor recovered unique artifacts and coins from a 1600-year-old shipwreck.

A fortuitous discovery by two divers in the ancient port of Caesarea before the Passover holiday led to the exposure of a large and spectacular ancient marine cargo of a merchant ship that sank during the Late Roman period 1,600 years ago.

Many of the artifacts are bronze and in an extraordinary state of preservation.

This is the largest assemblage of marine artifacts to be recovered in 30 years, said an Israel Antiquities Authority spokesperson.
