It is the cathedral church of Milan, officially the metropolitan cathedral of the Nativity of the Blessed Virgin Mary; it is the cathedral of the archdiocese of Milan. Symbol of the Lombard capital, and located in the homonymous square in the center of the city, it took six centuries to complete. It is the second largest cathedral in Europe.
The plan consists of a nave with four side-aisles, crossed by a transept and then followed by choir and apse. The height of the nave is about 45 metres (148 ft).
The roof is open to tourists (for a fee), which allows many a close-up view of some spectacular sculptures.
The cathedral’s five broad naves are divided by 40 pillars. The huge building is of brick construction, faced with marble. Its maintenance and repairs are very complicated.
In 2015, Milan’s cathedral developed a new lighting system based on LED lights.
