Italy has the richest flea market and antique fair culture in Europe. Every city has a weekly or monthly market. Rome's Porta Portese is every Sunday. Arezzo's antiquariato is the first Sunday. Milan's Naviglio Grande is the last Sunday. Planning your trip around a market day can be the difference between finding a €10 vintage treasure and arriving at empty stalls. This calendar ensures you never miss a market.

The best finds are at markets tourists don't know about.
