|Church of Ognissanti|
It is reputed that Matilde of Canossa granted the Ognissanti church around 1080 to the Abbey of Polirone in San Benedetto Po. Others ascribe the donation to the Benedictines as a gift by Pope Adrian IV in 1159.
The present church and façade were completed by 1755, creating a new church with stood at right angles to the original structure. The belltower and the chapel of the dead retain some of the original Romanesque architecture. In 1797, the order was suppressed by the Napoleonic occupation and the church briefly deconsecrated.
The interior contains the following artworks:
- St Benedetto and St Scolastica surrounded by Saints and Angels by Ippolito Andreasi in presbytery.
