The region, located between the two arms, Kalamauki and Panteli, of the current river of Stomios (ancient Didymos), was occupied by the ancient big city of the Eteocretans, Praissos, which was one of the most important regions of Eastern Crete. It was built on three hills and was surrounded by a strong fortification wall, whose remains are saved in some points and in particular on the northeast of the big hill, where the chair of the city’s authorities was located. The third hill with the altar-shrine and the holy cave in the position Skales were located outside the fortification. After the conquest of Crete from the Dorians in the 12th century B.C. the Eteocretans, who were the first inhabitants of Crete and the “native Cretans”, withdrawled towards the east of the island, where they preserved their genuine Minoan character, their language, religion and the worship of Diktaios Zeus. Praissos was located at the centre of the Sitia peninsula and had harbours in the Northern sea, the Cretan sea, in Iteia (Sitia), in the Libyan sea, in Styles, as it appears in the resolution of Praisians, during the Macedonian years, concerning fishery and the trade of the red shells and the navy. The Ierapytnians, who were of Dorian origin, after many of years of war finally defeated the Eteocretans of Praissos and destroyed their city. The region was probably inhabited since the Neolithic period. In the cave located in Skales, by the river banks of Kalamauki and Panteli, Neolithic and caramaic ceramics were found.
