Santa Maria Immacolata del Istituto Massimo is a dependent chapel of the parish of Santi Pietro e Paolo , and is located at Via Massimiliano Massimo 7, which is in the west end of EUR.
It belongs to a school run by the Jesuits, transferred here in 1960 from its former home at what is now the Palazzo Massimo alle Terme. The dedication of the original church at the latter, Santa Maria Immacolata al Collegio Massimiliano Massimo, has been preserved.
The modern chapel and assembly hall is a notable landmark in this corner of EUR. The architects were Studio Passarelli, and the work was completed in 1992. This is a large chapel, having an exterior plan based on an irregular hexagon with a long, parallel-sided pentagonal block attached at the entrance end. The exterior screen walls are blank and in yellow brick, the lighting being by large loeuvres in the roof. The interior arrangement is fan-shaped, with the seating focused on the main altar placed in an angle of the hexagon.
