The remarkably well-preserved wreck of a 2,000-year-old ancient Roman ‘sewn ship’ that was stitched together using ropes and wooden nails has been found in Croatia. The vessel was unearthed from the Porta de Mar archaeological site on the ancient waterfront of the town of Poreč, where it had sunk near an ancient pier. Two thousand years ago, Poreč was part of the Roman province of Dalmatia and the town’s shielded harbor made it ideal for both defense and maritime trade. Experts are calling the ship Croatia’s greatest archaeological discovery of the century — one that is shining light on ancient shipbuilding practices.
