Universally called San Pietro, the mother church Madonna del Rosario is a religious building in the city of Pozzallo. The square on which the building stands is called Piazza San Pietro, since the first parish depended directly on the cathedral of the same name in Modica.
The construction of the building began in 1876 by will of the Reverend Vincenzo Ferreri and continued during the regency of Don Alessandro Giannone, who subsidized the completion of the first order of the facade in 1891, and which he had consecrated to the Madonna del Rosario, to whom he was particularly devoted. The works ended in 1937, with the addition of the apse, two side chapels and the second order of the facade.
On 15 September 1958, Our Lady of the Rosary was proclaimed Patron Saint of the city, and is celebrated annually every 7 October.
The church, in the shape of a Latin cross, is divided into three naves. The side naves are separated from the central one by a series of square-shaped columns. Inside them there are numerous statues and paintings. In the apse there is the statue of the Madonna del Rosario, a late 19th century work in Lecce papier-mâché by Luigi Guacci, and two works on canvas by the Pozzallo artist Roberto Porcelli.
The devotion towards Our Lady of the Rosary is still deeply felt by parishioners today. To date, there are two parish priests who take care of the ecclesial community, Don Salvo Bella and Don Paolo Catinello.
