Kato Petali is located east of Apollonia. When viewed from afar, the village appears to stand proudly on a small hill. The settlement spreads around a central paved square, where the beautiful church of Zoodochos Pigi with its tower-like bell towers stands.

Here in the central square of the settlement, some of the events of the Cultural Association of Sifnos take place, such as music and theatre performances, reenactments of traditional Sifnian games, etc.
