Masterpiece of the Romanesque architecture in Lombardy, this church has a majestic nave and two aisles, surmounted by the lantern and its façade is richly decorated with sculptures, bas reliefs and figures of animals, plant volute cornices and green shoots.

The present church was built on the site of a previous Lombard church and was the coronation place. In fact Frederich Barbarossa was crowned here in 1155.

The inside boasts capitals showing biblical stories, allegorical figures. The crypt is greatly attractive.

The mosaic floor in the presbytery shows the “Months” and the “Labyrinth” and the transept contains Teodote’s crucifix, a silver-laminated masterpiece by a skilled goldsmith, who worked in northern Italy in the second half of the 10th century.
