An excerpt from the article 27 facts about Santorini

It is a place with a perfect view of the panorama. From here, ancient soldiers were scouting for approaching enemy ships.

At first, it was used by the Greeks, then the Venetians who built a fortress of strategic importance on the Sykros Mountain. Around the defensive infrastructure, islanders built a settlement of about 200 houses. Until the eighteenth century, the settlement was the island's capital. The fortress and village were utterly destroyed during numerous earthquakes.
