More than four hundred churches and thirty monasteries are an undisputed testimony that the people of this beautiful Cycladic island have deep faith. The Sacred Pilgrimage of Panagia Ekatontapiliani receives each year thousands of visitors, while the visitors’ interest is attracted by the well-cared Byzantine and post-Byzantine monuments that are scattered all over the island. The traditional festivals are a unique experience, which are closely related to Greek religious tradition, and attract lots of people throughout the year.
