Sacro Cuore Immacolato di Maria (Sacred Immaculate Heart of Mary), is a titular church in Piazza Euclide, Rome. It was built by the architect Armando Brasini (1879 - 1965). Its construction began in 1923 with the design of a Greek cross inscribed in a circle with an articulated facade, and completed before 1936, the year in which it was made a parish church and granted to the Congregation of Missionary Sons of the Sacred Immaculate Heart of Mary, usually known as the Claretians. (A grand dome was planned, but never realised - a smaller drum was completed in 1951.)
In the baptistry there are modern paintings by the Armenian Gregorio Sciltian (1900-1985).
Pope John XXIII elevated it to the rank of Minor Basilica in May 1959, and Pope Paul VI made it a titular church in February 1965, with Ángel Herrera Oria as the first titular. The present titular priest is Julius Riyadi Darmaatmadja S.J., appointed in 1994.
