Byzantine shipwreck off Croatia yields largest gold treasure ever found in Mediterranean

Uncovered in 2014 near Mljet island in Croatia, a Byzantine shipwreck dating back to the 7th-8th century has revealed more than 450 grams of gold, which includes coins, four belt buckles adorned with emeralds and rubies, and a gold signet ring belonging to Emperor Heraclius (610-641). Archaeologist Igor Miholjeck highlighted that this is the most significant gold discovery from a Mediterranean shipwreck. The vessel likely served a high-ranking Byzantine official traveling between Constantinople and the Adriatic. Found at depths exceeding 40 meters, the wreck also contained amphorae, ceramic jugs, merchant scales, and ivory game pieces, suggesting both trade and diplomatic missions. The Mljet wreck stands as one of the few well-preserved archaeological sites from this era, essential for studying Byzantine maritime routes.
