The first nucleus of the Infirmary was built by the will and contribution of donna Elena della Bronda in the mid-17th century. The building, intended to receive and assist the sick, poor and needy, was entrusted to the Observant Franciscan Friars of St. Peter of Silki. The complex was included in a block with a high concentration of housing and commerce, located near the first settlement core of medieval Thatari. The cafeteria and chapel spaces refer to the 17th-century phase; the complex was later transformed between 1892 and 1896. In the 19th century the Infirmary passed from the government of the Conventuals of St. Peter’s to the Carmelite fathers. In 1866 the municipality decided to use the building and garden as a kindergarten. Located a few steps from the Capuchin Nunnery, in the widening that leads to the nearby church of Sant’Apollinare, the building rises three stories high and has basements and an indoor garden. Over the years, the building has incorporated pre-existing buildings that testify to the fervor of daily activities and commerce, for which rooms such as warehouses, ovens, and cisterns were intended.
