The first inhabitants were Ardiaei,Illyrian tribe, who, through the port Prapratno on the peninsula Pelješac, came to Mljet approximately 4000 years ago. The first contact they had with the island was in ports Sobra and Okuklje because they were the nearest to Pelješac, but they also had contact with ports Polače and Kozarica. Arriving on a fully wooded island, they slowly settled close to the drinking water sources and along the edges of the island\'s valleys. They lived in small dwellings built of stone walls, while they were covered by underbrush and pine branches. They were farmers, dealt mainly with goats and sheep farming, hunting and fishing.
