Santa Maria Immacolata alla Giustiniana is a modern parish church at Via Cassia 1286, in the centre of the suburb of La Giustiniana north-east of the Circonvallazione Settentrionale. Picture of the church at Wikimedia Commons. 
This church is in the municipality of Rome, but belongs to the diocese of Porto Santa Rufina.
The blank, gabled and roughly rendered façade is yellowish brown with hints of grey, and has no windows. It has slightly battered sides, revealing the end walls of the actual church building. On it is a bronze statue of Our Lady, surrounded by twelve stars arranged as an arch. There is a simple cross above this, in the gable. The rather complicated entrance porch is open, and has a frame in grey stone with a triangular top, enclosing a blank tympanum in darker grey.
