Milan (population 1.3 million) is the second largest city in Italy and the capital of the region of Lombardy. It was founded by the Insubres, a Celtic people, before being captured by the Romans and being made capital of the Western Roman Empire. Milan flourished as a city under Roman, French, Austrian and Italian rule and remains the main business and industrial centre of Italy. It is especially known for its fashion and design houses, and is much-visited for its museums, theatres and architectural gems such as the Church of Santa Maria delle Grazie, which is decorated with Leonardo da Vinci paintings. Milan Fashion Week is one of the highlights of the fashion calendar and the Milan Furniture Fair is the largest such event in the world.
