Two staircases provide access to the gantry of the church, where a statue of
Saint Anthony of Padua stands holding the
Christ Child. Inside, the church is constructed of three
naves, divided by two columns of pillars made of pink marble. The general decoration of the church was done by Friar Bonaventura Loffredo da Alghero in 1889–1890. The fresco of the apotheosis of the Franciscan family in the apse area of the sanctuary was done by Friar Loffredo. The paintings of the side altars were done by various artists, mainly Franciscan:
St. Clare of Assisi by Giuseppe Bravi (1844–1908);
St. Francis of Assisi by Franz De Rhoden (1817–1903);
Japanese Martyrs crucified in 1597 in Nagasaki by Cesare Mariani (1826–1901);
Immaculate Mary by Francesco Szoldatiez (1916);
St. Ludovico di Tolosa by Eugenia Pignet (1940). Other paintings were done by the friars Giuseppe Maria Rossi, Caio D' Andrea and Michelangelo Cianti. == List of cardinal priests ==
