Agia Theodoti Attraction
Ios has a total of 365 churches and Agia Theodoti is the oldest and one of the most beautiful. It was built during the 16th century on top of the ruins of an ancient temple of god Apollo, parts of which can still be seen, and you will find it at the edge of Chora, close to the so called Homer's Grave. Near by are the ruins of an ancient aqueduct which you can also visit.
