The Church of Ognissanti is a Catholic place of worship in Rome (Italy), located in the Quarter Q. IX Appio-Latino, along Via Appia Nuova, near Piazza Re di Roma; it is the seat of the homonymous parish entrusted to the Sons of Divine Providence.

There the priest built, as the center of pastoral life, a small chapel dedicated to All Saints: due to the increasing number of faithful, it was later replaced by a larger parish complex.

[4] On 7 March 1965, Pope Paul VI made a pastoral visit to the parish and celebrated Mass in Italian for the first time, using the first post-conciliar version of the Roman Rite, which involved the use of the vernacular only in some parts, while reserving the Latin to the others (including the Canon).

In the upper part, in correspondence with the central nave, there is a large trifora inscribed in a round arch, while in the lower one there are three portals, each of which is surmounted by a lunette decorated with a marble bas-relief: the one in the center depicts the Glory of Mary, the lateral ones two Angels.

[4] The central nave ends, beyond the transept, with the semicircular apse, crowned by an ambulatory that houses the pipe organ, built in 1965 by the Pinchi company (it has an electric transmission with multiple system, 18 stops on two manuals and a pedalboard);[12] the upper part is decorated with a mosaic depicting the Trinity, Mary Immaculate and All Saints by Silvio Galimberti (1920).
