The Byzantines used to call castles, the towns that were surrounded by walls. Thus, according to this definition, we present the castles of Crete, with the greatest of all being the Big Castle of Candia (today’s Heraklion). There were several smaller fortified towns, such as Chania, Rethymnon, Sitia and Ierapetra, mainly walled during the Venetian Era.
A small castle was located near the village Sitanos of Sitia Region, namely Skalia. Skalia was a small village with a few residents built atop a mountain slope, where the outer walls of the houses formed a wall that surrounded the village, while from the north it was protected by cliffs.
