=== Fortifications ===
During the 15th and 16th centuries, the Cyclades were under threat from pirates who plundered the harvests, enslaved men and women and sold them in the slave markets. The small bays of the island were also ideal as hideouts. In response the islanders built their settlements at the highest, most inaccessible points, and very close to, or on top of, each other; while their external walls, devoid of openings, formed a protective perimeter around the village. In addition the following additional types of fortifications were built throughout the island to protect the island's inhabitants.
*'''{{lang|el|Casteli}}''' (castles), also written as kasteli, were large fortified permanent settlements. There were five on the island, Agios Nikolaos (at Oia), Akrotiri, Emborio, Pyrgos, and Skaros. At the entrance to every {{lang|el|casteli}} was a church dedicated to Agia (St.) Theodosia, the Protector-Saint of castles.

There were four goulas on the island. They were used both as an observatory and as a place of refuge for the islanders. They had thick walls, parapets, an iron gate, murder holes, and embrasures.
*'''{{lang|el|Viglio}}''' were small coastal watchtowers, which were permanently garrisoned, from where a watch was maintained and an alarm raised when a pirate ship was sighted.
