It is said to have been the oldest church in Milos. Nowadays, even though it is ruined standing without a roof, it remains impressive. It is built of well-chipped fragments of perlite perfectly hinged. Icons, iconostases and relics were removed from the church after the abandonment of Zefyria and it was broken apart in order for other churches to be built with the stones of that church. According to the tradition, some impious man put a dynamite to demolish the church and take the stones, but he only shattered the dome of the roof. His mules refused to go near the place and carry the giant stones, which you will see today inside the church.
