Mercato Campo dei Fiori: Mercato Campo dei Fiori is probably the oldest market in Rome. Since 1869, local farmers and vendors fill the Campo de’ Fiori square every morning except Sundays to offer all kinds of fresh food: fruit and vegetables, meat, fish, artisanal cheeses, traditional sweets, and more. Far from aiming to become a tourist attraction, this market still keeps its main goal of providing locals with local products. And, precisely for this reason, walking from stand to stand is one of the best ways to see and experience the most authentic Rome.
