When the
Saracens burned the
Abbey of Farfa in 898, a group of refugees settled in Rome. Some monks remained in Rome even after their abbot Ratfredus (934–936) rebuilt the abbey. By the end of the tenth century, the Abbey of Farfa owned in Rome churches, houses, windmills and vineyards. A bull of Holy Roman Emperor
Otto III in 998 confirms the property of three churches: Santa Maria, San Benedetto and the oratorio of San Salvatore. When they ceded their property to the
Medici family in 1480, the church of Santa Maria became the church of St. Louis of the French. Cardinal
Giulio di Giuliano de' Medici commissioned Jean de Chenevières to build a church for the French community in 1518. Chenevières' design was for an octagonal, centrally planned edifice. Building was halted when Rome was sacked in 1527, and the church was finally completed in 1589 by
Domenico Fontana and Giacomo della Porta, who designed the façade, according to an entirely different design. The church was consecrated by the Cardinal François de Joyeuse, Protector of France before the Holy See, on 8 October 1589. The interior was restored by
Antoine Dérizet between 1749 and 1756. The foundation '''' is responsible for the five French churches in Rome and apartment buildings in Rome and in
Loreto. The foundation is governed by an "administrative deputy" named by the French Ambassador to the
Holy See. ==Exterior==
