Ivrea Castle (1357), built during the reign of
Amadeus VI of Savoy. It has a quadrangular plan in brick with four round towers at the corners. In 1676, a tower, used as an ammunition store, exploded after being struck by lightning. It was never rebuilt. Once a prison, the castle today houses exhibitions. •
Ivrea Cathedral, which originated from a church built here in the 4th century at the site of a pagan temple. Around AD 1000, it was reconstructed by bishop Warmondus in
Romanesque-style: of that edifice the two bell towers, some columns, and the frescoed crypt remain. The latter houses an ancient Roman sarcophagus which according to tradition, preserves the relics of
St. Bessus (co-patron of the city together with
St. Sabinus). In 1785, it was rebuilt again in a
Baroque style. The current neo-classical façade was built in the 19th century. One of the old frescoes of the interior is the
A Miracle of the Blessed Pierre de Luxembourg (second half of 15th century). The sacristy has two altarpieces by
Defendente Ferrari. The cathedral also houses the tomb of
Blessed Thaddeus McCarthy. • The Biblioteca Capitolare ("Capitular Library"), near the cathedral, houses an important collection of codices from the 7th–15th centuries. •
