Built on an imposing rock mass in a panoramic position overlooking the surrounding town, consecrated and opened for worship in 1454, the Church of San Gregorio Magno in Savoulx, a hamlet of Oulx, has maintained a certain stylistic homogeneity, with Romanesque and Gothic elements and a 1662 intervention relating to the reconstruction of the apse area. Its exterior is characterised by a slender bell tower with a spire, while the façade is embellished with a stone portal dating back to 1532.

The high altar, with the rich wooden retable carved, is assigned to Jacques Jesse of Embrun in the coming years to 1662, the impressive cantoria instead dates back to 1555. The recent restoration has brought to light in the left nave a frescoed cycle of the second decade of the sixteenth century attributed to the Maestro di Savoulx, depicting scenes from the life of Sant’Antonio Abate, while on the side wall there are frescoes more fragmentary depicting God the Father, Santa Caterina d’Alessandria and scenes from the life of the Virgin.
