The church was built thanks to donations from Galiot de Genouillac in 1540, as commemorated by an inscription in a cartouche near the south portal. The work progressed slowly, so much so that in his will of 1545 he stipulated that it had to be completed "according to the portrait with which it was begun, both as regards the building and the roof."

Public place, accessible from the side. It was in the 11th century, in a primitive Romanesque style, that this chapel was built on a property belonging to the order of Cluny. It is dedicated to Saint Mamert, one of the first bishops of Vienne, whose tomb is kept in the former church of the Abbey of Saint-Pierre in Vienne, now a lapidary museum. Around 470, Saint Mamert had instituted the Rogations in order to protect agriculture from the frosts: these were processions that took place during the 3 days preceding the Ascension. It is part of the popular tradition of the saints of ice with Saint Pancrace and Saint Servais (11,12 and 13 May).
