The parish complex of the Immaculate Heart of Mary represents for Villaggio Mosè a very important hub of social and cultural aggregation. Historically the residential area of sulphur miners, Villaggio Mosè is marked by disordered building in which the church stands as a centrality, playing a strong catalysing role. The project evokes the theme of the virgo ecclesia facta, the Virgin made church, who, opening her mantle like a tent, gathers beneath it the faithful who form the single body of Christ.

The volume of the church is defined at its entrance by a great cut, a fissure that welcomes the faithful and generates the churchyard, a shaded space acting as a pause before entering the hall. The hall holds about 350 seats and generates an enveloping space, central in plan yet always oriented towards the presbytery. Inside, a four-metre-high base clad in stone relates the space to the human scale and refers to the theme of the cave: its texture recalls that produced by the extraction cuts of the stone blocks.
