The church of Agios Dimitrios, is a four-aisled basilica which seems to have been the bishopric of Ario for a certain period of time. One aisle remains and it has a dome. The aisles were separated with arches and columns. Externally there are blind arches decorated with bricks and the door has an interesting toothed arch above it. Agios Dimitrios has been built on the foundations of an ancient temple of Artemis. To reach the church take the road branching right from the centre of the village and turn right again. The church is on the road.
