Visitors are allowed to walk on the roof of The Cathedral, Milan, Italy.
Milan Cathedral (Italian: Duomo di Milano) is the cathedral church of Milan in Lombardy, northern Italy. It is the seat of the Archbishop of Milan, currently Dionigi Tettamanzi.
The cathedral is famous throughout the world for its significance in the promulgation of the Christian faith, for its role in the establishment of Catholic traditions of worship, its outstanding musical heritage and the splendour of its Gothic architecture.
Built from the late 14th well into the 19th century (and in a sense, never completed as work continues), the Duomo di Milano is one of the world's largest churches, being second in size within Italy only to Saint Peter's Basilica in Rome, and being the second largest Gothic cathedral in the world, after the Cathedral of Seville in Spain.
