CaltanissettaSutera.
The territory has been inhabited since prehistory .The Arabs fortified the site, while the town began to develop at the foot of the mountain in the area of the present-day quarter of Ràbato. In l366 it became a domain of the Chiaromonte family, who promoted the development of the town until the 16th c., when many of its inhabitants left for other recently founded centres (Acquaviva, Campofranco, Caltanissetta). In 1905 a landslide on Monte San Paolino seriously damaged the urban structures; this mountain, with its unusual cusped shape, provides an unforgettable image of itself and of the town at its foot.

The Town Hall, the Chiesa di Sant'Agata (l5th c.) and the Convento di Santa Maria delle Grazie all stand in Piazza Umberto I; further along to the left are the ruins of the 17thc. Chiesa di Santa Maria degli Agonizzanti. The Chiesa di San Giovanni, containing fine stuccos of the Serpotta school, is in Piazza San Giovanni. Along Viale del Carrnine we see the Chiesa del Carmine in the square of the same name; the church contains a marble statue of the Madonna del Soccorso (1503) and a wooden statue of the Blessed Mary (1696). Further along still, we come to the Chiesa Madre, dedicated to Our Lady of the Assumption. The Sanctuary of San Paolino and the former Convent of the Philippine Fathers (17th c.) are at the sumrnit of Monte San Paolino; at the end of the right-hand aisle of the church there are two precious silver reliquaries: the ums of St Paolino, 1496, in late Gothic style, and of St Humphrey, 1649, in baroque style.
