Natività di Nostro Signore Gesù Cristo a Casal Morena is a tiny chapel hidden away in trees near the Casal dei Romalli at Via Anagnina 396 in the suburb of Morena, part of the district of Casal Morena.
It was in the diocese of Frascati, but is apparently now deconsecrated after being made redundant by the building of Cristo Re a Morena nearby.
The original church for the area and until 1953 the only one, it was built for agricultural workers in the 17th century. The façade has a doorway with a triangular pediment, an oeil-de-boeuf window above and a large triangular pediment on top. However, a glance at the body of the chapel reveals that the façade is false, and the pediment is well above the roofline.
