At Kommos, above the famous beach in the south of the prefecture of Heraklion, there is the archaeological site of the Minoan city of Komos. Kommos in Minoan Crete was one of the two ports of the Minoan palace of Phaistos. Matala was the other one.
Excavations of the archaeological site began for the first time in 1976 by a group of Canadian archaeologists, but the existence of Kommos and its connection to the palace of Phaistos was known by Sir Arthur Evans. The finds include the harbor settlement, and public buildings such as shipyards, warehouses, prytaneion, temple and an amphitheater building. One of the most important finds are the ancient olive oil presses, which reveal how developed was the cultivation of olive trees in Minoan Crete.
The archaeological site is not accessible but you can admire the building findings outside the fenced area which is accessible from the road leading to Kommos beach.
