The Conservatory of the Daughters of Providence dates back to 1831. Former college for nobles, in the 19th century it became home to a charitable institution for orphans. Its wide Neoclassical facade dominates the east side of Piazza Indipendenza.

The Conservatory was originally located in a house in Via San Giuseppe (Castello district) and was supported by city charity and state aids. The institute was born on the initiative of Father Gian Battista Vassallo of the “Compagnia di Gesù” (Jesus Company), in order to accommodate poor girls, educating them in a Christian way and teaching them the necessary works to become good mothers.
In 1822 the Viceroy Count D'Agliano introduced several reforms, that aimed at improving the institution and he appointed the priest Lorenzo Frassetto da Nulvi as administrator. A weaving factory was set up and the boarders were trained in this work. The growth of the institution made it necessary to find a new area. The government gave to the Conservatory the old building of the College of Nobles, located in Piazza Indipendenza. It was rebuilt and adapted to the new requirements by the engineer E. Marchesi and it was occupied from 1831.

Sister Giuseppina Nicoli (now beatified) taught here from 1885 to 1889. The girls' school was open until the end of the 90s.

Nowadays the building is closed.

The archaeological complex of Saint Saturno is characterized by the presence of a church and a funeral area around it, which can be accessed from the current Piazza San Cosimo. The burial area is located in the northern side with respect to the church, and houses part of the necropolis including mausolea, sarcophagi, tumuli (grave mound) and tile-built tombs.

The area was used as a necropolis since the late Republican Age. Subsequently, it was conspicuously exploited with the same purpose by the local christian community, although the archaeological and epigraphic evidences of that use cannot testify a continuity throughout the ancient times.

The remains found at the adjacent church of Saint Lucifero bear witness of a burial use, whose link to the preexisting structures in the area of Saint Saturno and to the well of Saint Cosimo is still unknown.

The burial purpose, with respect to the different uses of those areas, reveals the complex problem of their distribution and dating: in fact, some recent excavations in the area opposite the Basilica of Saint Saturnino, currently housing a newly constructed square, have brought to light a quadrangular well that lets assume a sacred function within the hypogeal worship of water.
