Siena. 17 states in one city

Let's visit medieval Siena and immerse in the mysterious world of the Contrade. But what are they? Contrade are both districts of the old city and close-knit communities. They emerged in the Middle Ages, for troops supply and recruiting. 
All significant events in the lives of the Sienese — births, weddings, holidays — take place within their native Contrada. 
Each one has its own museum, fountain, square, and church. A contrada preserves its flag and motto — much like a small state.
