Oros Panagia

Panagia, in Medieval and Modern Greek, is one of the titles of Mary, mother of Jesus, used especially in Eastern Catholicism and Orthodox Christianity.

Most Greek churches dedicated to the Virgin Mary are called Panagia; the standard western Christian designation of "St. Mary" is rarely used in the Orthodox East, as Mary is considered the holiest of all human beings and therefore of higher status than the Saints.
