St. Michel, MONT, an insulated granite rock of conical form off the department of La Manche in Normandy, 18 miles W.S.W. of Avranches. Its steep ascent from the surrounding sands to a height of 242 feet, where it terminates in a platform on which there are buildings, gives it a very picturesque appearance. A temple or fortress attributed to Druids existed here at a very early date, and in the 8th century a Benedictine monastery was erected on the spot where St. Michael had appeared in a vision. The castellated buildings of the abbey range in date from the 12th to the 16th century. At the foot of the mount there is a town of about 400 inhabitants. For considerable periods the buildings have been a State prison, and Cardinal Ballue and Armand Barbes (q.v.) were among those confined here.
