San Luigi Grignion di Montfort dei Monfortani is a 20th century convent church at Via Prenestina 1391 in the small suburb of Colle dei Monfortani in the Torre Angela district.
The dedication is to St Louis Grignion de Montfort.
The church belongs to the Company of Mary or Monfortani, a missionary congregation founded by the patron saint and is attached to the Centro Mariano Monfortano. This is an institution dedicated to the promotion of Mariological studies. The church also provides a pastoral outreach for the rather isolated and self-contained suburb.
It is dependent on the parish of San Massimiliano Kolbe.
The little church is on a rectangular plan and is shaped like a prism. The façade is hence in the shape of a triangle, most of which is taken up by a very large triangular window with narrow vertical bars and decorated by horizontal rectangular panels in a semi-random pattern. The façade either side of the entrance, below the window, is in pink brick.
