This Catholic church was founded by Saint Francis of Assisi during the 18th century. Around 1860 it switched to the Orthodox denomination and soon afterwards a grand cathedral was constructed with a Byzantine dome. In 1957, this structure replaced the former basilica. I enjoyed the wavy cornice accented by the red roof tiles and the exaggerated dentil molding on the Church of Mother of God Sissiotissa. Each March 25 the Annunciation of the Virgin Mary religious festival is held on the seven Ionian Islands. It is part of several annual celebrations called the Eptanesian Traditions.
