The site was initially occupied in the twelfth century by a hospice and chapel of the Knights Hospitaller of the Order of Malta, under the jurisdiction of the priory of Saint-Gilles in Provence.

The thirteenth-century church formed part of a priory of the same order situated in olive groves outside the city walls of Aix.

In the 17th century the parish was incorporated within the city of Aix when the ramparts were extended to the south and the adjoining lands of the priory sold off to help create the quartier Mazarin.

In three smaller quatrefoils below are three knights hospitaller of Malta: Berenger Monachi (l.), Gerard Thom (c., founder of the order) and Hélion de Villeneuve (r.).

At the base of the window are six thirteenth century coats of arms connected with the Order, including those of Provence, Malta, Aragon and Aix.
