Churches, monasteries and picturesque chapels that preserve their simple beauty with all humility have been sown all over the island of Kimolos. The most impressive religious site is the cathedral, the church of Panagia Odigitria dedicated to the Virgin, the patron saint of Kimolos. The locals built this church between 1867 and 1874 where a religious feast takes place every year, on November 21st.
The Byzantine churches of Panagia Evangelistria, Agios Taxiarchis (17th century), Chrissotomos (17th century), Agios Spyridon and Panagia Konomou (17th century) are all worth visiting monuments that give a taste from the past. Inside the castle walls (Mesa Kastro) is the chapel of Agia Methodia, and the Church of the Birth of the Christ built in 1592. Every church in Kimolos is a part of the island's history and on the name day of their saints, various festivals are held in the central square.
