If all things old fascinate you and you don't have the money to spend on antiques, then this open-air market is just the place for you. Musty old books, Roman souvenirs, coins, stamps and jewelry are what you will find here. The street is choc-a-bloc with little shops, and vendors are almost shouting out Italian phrases to entice you into making a quick purchase. Be prepared to haggle, though in Italian, maybe!
