Fátima, Portugal
In her "Memoirs", the Portuguese Carmelite nun Sister Lúcia, seer of Our Lady of Fátima, tells that, between April and October, 1916, an angel appeared three times to her and to Francisco and Jacinta Marto, in Fátima, Portugal, inviting them to prayer and penitence. The angel identified himself as "the Angel of Peace" and "your country['s] ... Angel Guardian, the Angel of Portugal."
