the duomo is one of the main example of 12th century romanesque architecture in northern italy. its façade features three orders of loggias and is flanked by a tall gothic tower in brickwork built in 1294.
the inside is divided into a central nave and two aisles by beautiful columns that also support the women's gallery. the presbytery stands exactly on the crypt and is above the floor level.
the walls in the aisles are decorated with some precious 16th century frescoes. in the dome you'll see a masterly composition made by correggio between 1526 and 1530.
on the right wall of the right branch of the transept there is the well-known "deposition" by benedetto antelami (1178).
