You walk along the main street in Ia and turn left down the narrow alley. Go to the end and then turn left again and it's right there. You can't miss it. Blue domes in the foreground and Imerovigli and Fira in the distance.
This is the biggest church in Ia. It's got six bells and all but the top one have a rope so they can be rung.
Easy, in-the-camera panorama of Ia taken from the castle which is actually a series of ruined buildings on High Point at the West End of the village.
