Duomo di Milano

Piazza del Duomo ("Cathedral Square") is the main piazza (city square) of Milan, Italy. It is named after, and dominated by, the Milan Cathedral (the Duomo). The piazza marks the center of the city, both in a geographic sense and because of its importance from an artistic, cultural, and social point of view. Rectangular in shape, with an overall area of 17.000 m² (about 183.000 Sq Ft), the piazza includes some of the most important buildings of Milan (and Italy in general), as well some of the most prestigious commercial activities, and it is by far the foremost tourist attraction of the city.

While the piazza was originally created in the 14th century and has been gradually developing ever since (along with the Duomo, that took about 6 centuries to complete), its overall plan, in its current form, is largely due to architect Giuseppe Mengoni, and dates back to the second half of the 19th century. The monumental buildings that mark its sides, with the main exception of the Duomo itself and the Royal Palace, were introduced by Mengoni's design; the most notable of Mengoni's addition to the piazza is the Galleria Vittorio Emanuele II arcade.

The origins of Piazza del Duomo can be traced back to the vision of Azzone Visconti (lord of Milan from 1329 to 1339). In 1330, Azzone ordered the demolition of the taverns that circled the two central churches of Milan of the time, the Basilica di Santa Maria Maggiore and the Basilica of Santa Tecla, to create a market square, called "Piazza dell'Arengo", which is the first incarnation of what is now Piazza del Duomo. The piazza was named after the arengario (also known as the "broletto"), i.e., the seat of the local government. None of the original buildings of Piazza dell'Arengario has survived.

Milan Cathedral (Italian: Duomo di Milano) is the cathedral church of Milan, Italy. Dedicated to Santa Maria Nascente (Saint Mary Nascent), it is the seat of the Archbishop of Milan, currently Cardinal Angelo Scola.

The Gothic cathedral took nearly six centuries to complete. It is the fourth largest cathedral in the world and the largest in the Italian state territory.
