San Donnino or San Donnino Martire is a Romanesque style, Roman Catholic church in Piacenza, Region of Emilia Romagna, Italy. It is dedicated to Domninus of Fidenza.
History
A church was built on the site by the 12th century, but rebuilt in 1236 by Cardinal Jacopo da Pecoraria. The original structure is decidedly Romanesque basilica plan with three naves closed by semi-circular apses. The interior and the façade were remodeled in throughout the centuries. After a sudden collapse of the nave in 1951, the latest restoration removed many of the additions accumulated over the centuries. The choir and the sanctuary had been frescoed with quadratura by Francesco and Giovanni Battista Natali, with figures by Bartolomeo Rusca. The church houses the adoration of the Blessed Sacrament and holds a bronze crucifix by Giorgio Groppi donated by the baker's guild in town. It also held a canvas of St Anne, St Joseph, and other Saints by Bartolomeo Baderna.
An order of nuns is affiliated with the parish church. Little is known of San Donnino or Domnini, cited as a deacon of Piacenza in the early Christian period.
