Two and a half centuries ago, the residents of Milia, terrified by an epidemic that had occurred, asked for the help of Saint Cosmas of Aitolia. According to tradition, the Saint performed a request and circled the village three times. The third time he stopped on the eastern side of the village, a little after Agia Paraskevi, where he fixed an iron cross on the fork of a small pine tree.
The “Iron Cross” has been nesting in the fork of the pine tree for the last 230 years. A chapel was also built in honour of the Saint, with a panoramic view of both Mesaia (Middle) and Kato (Lower) Milia.
