Maria Pia Mastena was an Italian religious sister born in 1881 who dedicated her life to teaching and spiritual service. After initially seeking a contemplative life in a Cistercian convent, she transitioned to active ministry following guidance from her spiritual director. She eventually founded the Religious Sisters of the Holy Face, a congregation focused on assisting the sick and supporting future priests. Her work expanded significantly after World War II, during which her community provided impartial aid to all victims of the conflict. She died in Rome in 1951.
