Church of Saint Lucia, Catholic church in Della Vittoria district, Rome, Italy

The Iglesia de Santa Lucía en Piazza d'Armi is a modern religious building with clean architectural lines and functional design elements throughout its exterior and interior spaces. The structure follows a straightforward contemporary style that stands apart from older church buildings found across Rome.

Architect Tullio Rossi designed and completed this church building in 1938 as a deliberate break from traditional church architecture in the Italian capital. The project represented part of the modern movement that introduced new forms of religious construction in Rome.

The church is the seat of a parish erected on 22 May 1936 by decree of Cardinal Vicar Francesco Marchetti Selvaggiani, before the building itself was finished. Its cardinal title, Santa Lucia a Piazza d'Armi, was assigned in 1973. In the left aisle chapel stands a white marble statue of Saint Lucy by Francesco Nagni, set against a polychrome mosaic by Silvio Alessandri.

The church stands on the Circonvallazione Clodia, in the stretch between Piazzale Clodio and Piazza Maresciallo Giardino, in the Della Vittoria district. The entrance faces a forecourt (sagrato) reached from the street; the bell tower is at the rear of the building. The nearest reference points are those two squares, useful for orientation when arriving on foot or by bus.

The church has held the cardinal title "Santa Lucia a Piazza d'Armi" since 1973. Its pipe organ, Mascioni opus 907, was built in 1969 for the Pontifical Latin American College and donated to the parish in 1975 by the Carabinieri, Italy's military police corps.
