Mljet’s rich heritage continues into classical antiquity, adding depth to any Croatia yacht charter visit. From the 2nd century BC onward, the Romans left a significant imprint on the island, particularly around Polače, where the remains of a grand palace complex, an early Christian basilica, and Roman baths reveal that this sheltered harbour was once a prosperous settlement in late antiquity. Today, Polače remains one of the island’s most important anchorages, valued by sailors for its natural protection and direct access to these remarkable historical sites.

The island also holds a place in Christian tradition. While several Mediterranean locations claim to be the site of St Paul the Apostle’s shipwreck, many scholars identify Mljet — known in antiquity as “Melita” — as the place where he is believed to have spent three months following his ordeal at sea. Whether legend or fact, the story adds a spiritual dimension to an island already steeped in myth and history.

In the 12th century, Benedictine monks established a powerful presence on Mljet, constructing a Romanesque monastery on the tiny St Mary’s Island in the centre of the Great Lake. For centuries they governed the island and its inhabitants, shaping local life until Mljet passed to the Republic of Dubrovnik in 1410. The monastery still stands today, beautifully preserved and surrounded by tranquil water and forest, making it one of the most atmospheric cultural excursions available during a Croatia yacht charter. Reached by tender or local boat, it offers a serene combination of architecture, history, and natural beauty at the heart of the national park.
