San Giovanni Battista de Rossi, Catholic church in Appio-Latino district, Rome, Italy

San Giovanni Battista de Rossi is a brick church on via Cesare Baronio in the Appio-Latino district, built to a design by Tullio Rossi between 1938 and 1940. The facade, in exposed brick with a few travertine details, carries the coat of arms of Pius XII and a dedicatory inscription dated A.D. MCMXL, and is flanked by a bell tower. Inside, three naves are divided by square pillars under a trussed ceiling with exposed tiles; the central nave alternates paintings of the Twelve Apostles by D. Duili with large windows, and Alessandro Missori painted the apse in 1945.

Pope Pius XII commissioned the church in 1938 to designs by architect Tullio Rossi; construction ran until 1940, when it was erected as a parish on 26 July by decree of Cardinal Vicar Francesco Marchetti Selvaggiani. Consecration followed only on 22 May 1965, and the relics of Saint Giovanni Battista de' Rossi were transferred here the next day from Santissima Trinità dei Pellegrini. Paul VI made it a titular church on 30 April 1969.

The church houses the relics of Saint Giovanni Battista de Rossi, which were moved here in 1965 from another Roman church. This transfer made the location a special place for believers who venerate this saint.

The building is easy to reach by public transportation and sits in a residential area with nearby tram and bus stops. The church holds regular services and remains open to visitors outside of these times if you want to see its modern interior.

Pope Paul VI elevated the church to titular church status in 1969, granting it a special standing within Rome's church structure. This title made it one of several churches assigned a cardinal as protector.
