The celebration of the Apparitions of Saint Michael at Mont Tombe, Normandy, France to St. Aubert, Bishop of Avranches in 708 AD.

When St. Michael appeared the first time, Aubert thought it was a dream and dismissed it. Then the Archangel appeared a second time and again reiterated his desire that a church be built upon Mont Tombe in his honor. Aubert ignored the request a second time, not sure about the size of the church.

St. Michael then appeared a third time and sought to get Aubert’s attention by pressing his finger on Aubert’s forehead. He burned a hole in his head and Aubert quickly started to make plans for the church on Mont Tombe.

The initial church was founded on October 16, 708 and Aubert sent a request to Monte Gargano, where St. Michael had appeared in 490. He was able to secure two relics from Gargano, including a portion of a red altar cloth touched by St. Michael and a piece of rock from the footprints the Archangel left there.
