A plethora of whitewashed churches and monasteries adorn the island's countryside and coasts. In Kanala village, on top of the hill sits the Church of Panagia Kanala, the trademark of Kythnos and one of the most important pilgrimage sites in Cyclades, home to the miraculous icon of the Virgin. It used to be a monastery during the Byzantine times.
During those times many churches were founded including the church of Agios Savvas and Agios Minas with the brilliant carved iconostasis. A short walk away from the main village lies the remarkable 17th century Monastery of Panagia Nikous which is built on a fabulous location, on a high cliff over some ancient ruins. The fine church of Agios Ioannis Prodromos (John the Baptist) is perched on a low hill in Driopida. Also worth seeing in Chora are the churches of Agios Ioannis, Agia Triada and Agios Panteleimonas.
