On the summit of the Lindos Acropolis are the ruins of the goddess Athena Lindia, temples from the 4th century BC As well as the Propylaea, the great Hellenistic Stoa and the Byzantine chapel of Saint John. In the time of the Knights of St. John, the castle is surrounded by sturdier fortress walls while the flowering period of Lindos extends as a naval power up to the 19th century. According to myth, the cult of Athena Lindia was pre-Hellenic, although this is not borne out by the sporadic excavation finds. The history of the sanctuary begins in the Geometric period (9th c. BC). In the Archaoc period the tyrant of Lindos, Kleoboulos, revived the cult and built a temple, probably on the site of an earlier one. The Archaic temple had the same Doric tetrastyle amphiprostyle plan as the subsequent one.
