East, of Kato Petali, you will find the old monastery of Saint John the Chrysostomos (Saint John with the Golden Tongue), which was founded in 1650; according to local tradition, this was where the first Greek school on Siphnos was located, and where, too, the School of the Holy Sepulcher, known as the Helleno-museum, was housed before it was moved to the School building of Saint Artemios. South of the village, in the middle of an olive grove, you will find the beautiful church of the Virgin Mary of Koukia (1614), also known as Myrtidiotissa. Kato Petali has restaurants, a grocery store, a small convenience store and rooms for rent.
