Santo Spirito, Norman church in Caltanissetta, Italy.

Santo Spirito is a Norman church and monastery on the northeastern outskirts of Caltanissetta, along Strada Statale 122. The church has a single nave with three semicircular apses supported by pilasters, narrow windows, and a north side rounded portal. A 13th-century Gothic ogival portal leads to a defensive tower. The interior holds a Norman baptismal font and 15th-century frescoes.

Commissioned by the Norman count Ruggero and his wife Adelasia between 1092 and 1098, the church was consecrated in 1153, as recorded on a plaque on the left pillar of the main apse. In 1178 it was entrusted to the Augustinian canons, though the series of abbots began only in 1361. Fabrizio Moncada restored it in 1568, and in 1759 countess Ruffo Moncada gave the abbey to the Capuchin fathers, the last of whom died in 1904.

The abbey was entrusted in 1178 to Augustinian canons regular, and the series of abbots began in 1361. In 1759 Countess Ruffo Moncada handed it to the Capuchin fathers, the last of whom died in 1904. The church is still open for worship in the Diocese of Caltanissetta.

The church is open to visitors during daylight hours most days, though access may be limited during religious services and ceremonies. Those visiting should be prepared for uneven stone floors and steep historic stairs, and it is helpful to check current opening hours before arriving.

Inside, a 1st-century Roman cinerary urn belonged to Diadumenus, a freedman of Emperor Titus Flavius Caesar and probably owner of the land where the abbey later rose. The abbey also keeps the Crucifix of the Staglio, tempera on panel, held to be its most precious work.
