On March 25, the Church celebrates the moment the Angel Gabriel appeared to the Virgin Mary in Nazareth and announced that she would conceive and bear the Son of God (Luke 1:26-38). Mary's response — "Be it done unto me according to thy word" — marks the Incarnation itself, the instant when God became man. The feast falls exactly nine months before Christmas.
The event is inseparable from its geography. The Basilica of the Annunciation in Nazareth encloses the grotto where tradition places the encounter. In 1291, according to pious belief, angels carried the house of the Holy Family from Nazareth to Loreto, Italy, where it remains enshrined in the Basilica della Santa Casa. Replicas of the Holy House — the "Loreto copies" — spread across Catholic Europe from the 16th century onward: Prague, Walsingham, Maria Loretto in Austria, Hergiswald in Switzerland, and dozens more.
Florence venerates the Annunciation through a different tradition. At the Basilica della Santissima Annunziata, a 13th-century fresco of the scene was reportedly completed by an angel's hand when the painter fell asleep. The image became one of Italy's most venerated icons. At Varese's Sacro Monte, the First Chapel opens the entire pilgrimage cycle with the Annunciation scene in painted terracotta.
