The Sanctuary of St Michael Archangel is located in Monte Sant’Angelo on the Gargano. The Sanctuary is also known as the Celestial Basilica, since, according to tradition, it was directly consecrated by the Archangel Michael. The site where today’s sanctuary stands is very ancient and rich in anecdotes: from the pagan cult of the gods Calacant and Apollo, to the apparitions of St Michael between the late 5th and early 6th century.
