In the late middle ages Chieri was a prosperous municipality with a territory which included Asti, Moncalieri and Turin. It was controlled via a series of castles and a web of political connections precociously integrated into the Savoy-Acaia state (1347).
The patrimony of medieval art therefore saw a profound re-visitation in the 1500’s which incorporated and in large part substituted the preceding testimonials: this is true for the residual towers as it is for the more ancient palaces. The Santa Maria cathedral has only the Roman crypt remaining.
Among the other residual testimonials, often concentrated towards the end of the 1400’s, is the church of San Domenico, with it’s stone capitals inside and the clay palmettes of the facade. In addition to these there is the jewellery that constitutes the “Cathedral Treasure” and the famous reliquary of the head of San Giorgio in the church of the same name in Chieri, from the end of the 1400’s. Another type which has conserved more ancient traces is that of the illuminated decorations used in convents.
