Santa Maria Mater Dei is a modern parish church at Via della Camilluccia 120, in the Trionfale district north of Monte Mario. it is dedicated to the Blessed Virgin Mary under her title of "Mother of God" (Mater dei in Latin).
The parish is administered by the Sons of Divine Providence (the Orioni Fathers), who run a sports complex at this address.
The church is located off the road, and is rather hidden away. There seems to be little information available on it.
It was completed in 1978, on a rectangular plan without any special architectural features. The white exterior side walls are battered, and the roof is bright green with a very low pitch.
