Sixt Abbey

The Sixt Abbey is a former abbey of regular canons belonging to the congregation of Abondance Abbey located in Sixt-Fer-à-Cheval, in the department of Haute-Savoie in the region of Auvergne-Rhône-Alpes, France. Founded before 1144, it was closed in 1792 following the French invasion of the Duchy of Savoy. Only a portion of the original buildings survives today.

The church, its granary, the former abbatial building, and the presbytery are listed as historical monuments by a decree dated February 17, 1997. Since the early 2010s, the former abbatial site has been the subject of archaeological and historical research. The abbey played a significant role in fostering pastoralism in a high-mountain region during the Middle Ages.
