Milan is a city in northern Italy, capital of Lombardy, and the second-most populous city proper in Italy after Rome.

Milan's figurative art flourished in the Middle Ages, and with the Visconti family being major patrons of the arts, the city became an important centre of Gothic art and architecture (Milan Cathedral being the city's most formidable work of Gothic architecture).
