The abbey was rebuilt in the early 11th century by Gezo, abbot of Breme according to the Chronicon Novaliciense. In 1646 the Benedictines were replaced by Cistercian monks, who remained here until 1796, when they were expelled by the Piedmontese provisional government. A third refoundation occurred after the monks of a hospital established by Napoleon at the Mont Cenis (1802) moved back to Novalesa after the emperor's fall. However, they were again expelled in 1855 and the abbey's building auctioned under the laws of expropriation of the Piedmontese government. The complex was acquired by the province of Turin in 1972 and was revived in 1973 with the return of the Benedictine monks, who still live there.
