Ivrea - Duomo di Santa Maria

The first Christian church was built here at the site of a Roman temple in the 4th century. A tree nave basilica existed in the 9th century. A Romanesque cathedral was built, when Bishop Warmund (= Warmondo) had his episcopal see here, end of the 10th century. It is known, that this church had a "westwerk", following the Ottonian architecture, popular at that time north of the Alpes.

Alterations and rebuildings were undertaken in the 13th, 15th and 16th century. In 1785, it was rebuilt again in a Baroque style.
