|Sant’Ildefonso e Tommaso da Villanova is a subsidiary church of the parish of Sant’Andrea delle Fratte, at Via Sistina 11 in the rione Colonna.|
It is the church of a college run by the Augustinian Recollects, and was built for them in the 17th century. The original Recollects were Spanish, hence the dedication to two Spanish saints -Ildephonsus of Toledo and Thomas of Villanova.The façade, by Ferrari, was added in 1725. It is of two stories, separated by a dedicatory inscription, and is topped by a segmented pediment. There are two pairs of round-arched niches, one flanking the door with its segmented pediment and the other the single window above the inscription with its triangular pendiment.
The ceiling has a reticulated design reminiscent of Borromini’s work at Re Magi.
