Milan travel guide — where to stay, what to do, and where to eat in Milan, Lombardy, Italy.

Milan's history spans more than 2,600 years, from its founding as a Celtic settlement called Medhelan (meaning 'middle of the plain') around 590 BC, through Roman, medieval, Renaissance and modern eras. Under Roman rule as Mediolanum, it became the de facto capital of the Western Roman Empire in 286 AD. The Visconti and Sforza dynasties transformed it into one of Europe's most powerful Renaissance cities. It was the setting for Leonardo da Vinci's greatest works and became Italy's industrial and financial capital in the 20th century.
