A few kilometers after Sagkri village is one of the island's most important archaeological sites. Here, in the area of Gyroula, on a hill of fertile plains overlooking the inland and sea, the worship of the deities of nature began in around the 8th century BC.
During the reign of the tyrant Lygdami in 530 BC, a marble Ionic temple was built which was dedicated to the goddess Demeter. According to archaeologists, it is the precursor of classical Attic architecture. A three-aisled paleochristianic basilica was erected in 6th century AD, above the ancient temple.
Today, the church has been restored and the archaeological remains are open to the public daily at all hours of the day.
