Emporios is a small village with a hilly terrain 8km southeast of Mandraki with a few permanent residents. On the top of the hill we find the castle of Emporeios, its foundations dating from the Byzantine era, while the walls belong to the Knights of the order of Rhodes. Inside the castle, on the top of the hill there is the temple of Taxiarchis Michael, built in the late 13th century, with a carved wooden chancel and interesting wall painting compositions. The cave formed at the village’s entrance is a unique natural phenomenon as due its heat it is considered a natural sauna. It is an example of the intense volcanic activity on the island.
