It is a
titular church, since February 1965 when
Maurice Roy became its first
Cardinal-Priest.
Patrick D'Rozario has held the title since 2016. It was made a parish church, served by the
Congregation of Priests of the Most Holy Sacrament, by
Pope Pius XII. The Redemptorist Generalate is adjacent. The church was close to the Canadian embassy, until the embassy re-located in 2007. Initially, the church was named
Nostra Signora del Santissimo Sacramento (Our Lady of the Blessed Sacrament) but was re-consecrated in 1962. The church was designed around 1950 by Bruno Apollini Ghetti. The façade mosaic is by
Marko Ivan Rupnik. There is a small raccoon in the bottom right hand corner. The church contains a high altar designed by Francesco Nagni, ceramic decorations (including a fine crucifix) by Angelo Biancini. Biancini's terracotta ambo has panels depicting The Last Supper and the Madonna and Child. The stained glass windows are by
János Hajnal and Marcello Avenali. == Cardinal priests ==
