The
Benedictine monastery of Santa Maria ad Abbadia Alpina was founded in 1064 by Adelaide, Princess of Susa. In 1078, the Territorial
Abbacy nullius of Santa Maria ad Abbadia Alpina was established. It vested in its abbot the privileges of a diocesan prelate: that is, territoriality was not assigned to a bishopric. Instead, the abbey was directly subject to the
Holy See. From 1443, its residential ('claustral') abbots were replaced by
commendatory abbots, often secular, mainly interested in cashing the abbey's proceeds and earnings.
In 1805 it was suppressed. Its remaining territory was merged (as was the former bishopric of Pinerolo) into the
Diocese of Saluzzo, according to the wishes of the French emperor
Napoleon I Bonaparte.
