The central hub for the city's celebrations and festivities, this historic piazza takes its name from the looming cathedral that dominates the northeast edge of the square. It is significant not only for its geographic prominence, but also from an artistic, cultural and social point of view. The piazza is flanked by some of the most important buildings in Milan, and widely recognized as the preeminent tourist attraction in town. Originally built in the 14th century under the direction of Azzone Visconti, lord of Milan, the space developed over the passing centuries until it obtained, more or less, its current form from architect Giuseppe Mengoni in the second half of the 19th century. Today, the elegant arches and porticos that line the square and the imposing grandeur of the Duomo certainly make this the loveliest and most important spot to see in Milan.
