The Sisters of Charity of the Immaculate Conception of Ivrea (Suore della Carità dell'Immacolata Concezione d'Ivrea) was founded at Pinerolo near Turin in 1828, and established the large convent and school of Immacolata dei Miracoli near the Vatican in 1906. Then they took over the convent of Sante Rufina e Seconda in Trastevere in 1917. Back then, that locality was a poor working-class one which was appropriate for the ministrations of the sisters -it is very different now.
A large new convent on a suburban site was began as the congregation's Generalate (headquarters) in 1960, and a chapel added in 1973. The latter is an important work by the modernist architect Silvio Galizia.
The project was overly optimistic, although the sudden drop in vocations after the Second Vatican Council was perhaps impossible to predict. At present (2016) the Generalate is at Sante Rufina e Seconda, and the Aurelio convent is a residential care home for elderly sisters. It is also the noviciate, according to the Diocese.
There seems to be some doubt as to the future of this convent.
The plan is almost indescribable, being based vaguely on a logarithmic spiral or nautilus with a central tower and an outer wall with sections inwardly curved. The copper-sheathed roof is in sectors spiralling round the tower, which has a circular bubble skylight.
The building material is shuttered concrete, inside and out.
Unfortunately the chapel stands well away from the street, behind a wall. A glimpse of it can be had through a gate.
A look at Google Earth for the address is recommended.
