Traces of a Bronze Age settlement were found in the locality (1) and several Roman finds, including isolated burial tombs at unknown sites (2). " Magno Casale" is named for the first time in a map of 989 and later in the Bull of Stephen IX of the year 1057: "unum mansum in Magno Casale et Capella S. Silvestri cum dominicato", in the bubbles of Alexander II of 1072 and Alexander III of 1178 (3). The Monastery of St. Prospero in Reggio also belonged to the Church, as indicated in the Tithes of 1302 (4). The church was rebuilt by Francesco Zoboli in the first half of the 15th century (5).Several works were carried out under the rector Domenico Ferretti (1657-1709) (6). The visit of Bishop Marliani in 1663 shows the church as "antiquae structurae" and put on his face. It was rectangular in shape, with a nave with a choir to the east. In 1658 a new Baptistery was made. The ancient tower erected in 1650 was reinforced and raised again in 1672. In 1772 a new building was planned by P. Armani. The work was interrupted with the suppression of the confraternities; resumed in 1790 ended in 1793. The Church had reversed the orientation with a new facade towards the street. At the end of the 19th century, several interior and churchyard embellishments were carried out. The rectory built from 1830 to 1838 is restored in 1909 together with the church.
This has a sober facade punctuated by two pairs of lateral pilasters and concluded by a broken frontispiece. The interior is simple and majestic, with a single nave with six columns of Ionic order two to two intermezzate chapels on each side. The bell tower is a single-hole cell. In 1314 the Municipality of Reggio ordered that the men of Mancasale built a good "rosta" near the Church. The tower was occupied in 1345 by the Marquis d'Este and destroyed by the Gonzaga in 1354. In 1315 Mancasale with 22 "fires" was a slope of Reggio and in 1447 an autonomous municipality then joined to the capital (8). At the end of the eighteenth century it comprised 903 inhabitants (9).A privilege of the Emperor Charles IV in favour of Francesco Zoboli cites the concession to the aforementioned, in 1357, of the mill on the Naviglio (10). The mill "Chiesa" with the press is still indicated in the Hydrographic Map of Italy of 1888 (11).
