Every historical period haw left its trace on the land of Sitia.

After the Minoan era, the land of the Praesians kept its Minoan roots, although hemmed in by hostile Doric environment, until it was ruined by the mighty Hierapytnian city. After the Classical and the Hellenistic period, it was the Roman conquest that left its own traces. The Roman fish tanks at Sitia, the theater at Koufonisi, and other ruins testify to the importance of this area during that period.

During the Byzantine period, and later during Venetian rule, new forts, settlements, great ports, and big or small churches were built. The land of Sitia, doubtlessly an easy prey for pirates and bandits, keeps its important and cultural development uninterrupted.

The Kazarma fortress, the towers scattered all over the area, glorious building such as those in Etia and Voila, new settlements built on the ruins of previous ones, like the Lioretro fort, the Roman vigiliae (guard towers), spacious villas and mansions, strong walls and makeshift fortifications –those are just some of the Venetian traces that visitors will see wherever they go.​​​
