The Duomo di Monza, formally the Basilica of Saint John the Baptist, is a Lombard-Gothic structure housing the Iron Crown of Lombardy, a relic traditionally used for the coronation of the Kings of Italy. The building underwent significant expansion in the 14th century, resulting in the iconic black and white striped marble facade designed by Matteo da Campione. Its interior features extensive fresco cycles, most notably the 15th-century Zavattari Chapel, which depicts the life of Queen Theodelinda. The attached Museo e Tesoro del Duomo contains a vast collection of medieval artifacts, including ivory diptychs, gold-smithing, and early Christian relics. The bell tower, added in the 16th century by Pellegrino Tibaldi, complements the original medieval architecture. The site serves as the primary religious center for the city of Monza. The current structure stands on the site of an earlier oratory commissioned by Queen Theodelinda in the late 6th century.
