Duomo di Milano (Milan Cathedral) in Italy
Location: Milan, Italy
Architect: Nicolas de Bonaventure
Year Completed: 1965
Constant renovation and reconstruction have been underway on the Duomo di Milano for centuries. Saint Ambrose built a basilica on this site at the beginning of the 5th century, with an adjoining basilica added in 836. When fire damaged both buildings in 1075, they were rebuilt as the Duomo. Ground broke for the new Duomo di Milano in 1386. New construction and design projects were also initiated in 1762, and major cleaning and renovations were finished in 2009.
