Since the early 20th century, Piazza San Cosimato has been home to Trastevere’s modest but lively outdoor food market six mornings a week. Though smaller than other popular outdoor markets in the city, the San Cosimato market has a dedicated following; some of the vendor families have occupied a stall at the market since its early days, handing it down through generations. Shoppers can purchase local produce, fresh fish and meat, and artisan cheeses and cured meats. To learn more about the traditions of outdoor markets in Rome and the history of the San Cosimato market, join a food tour of Trastevere or a guided tour of the city’s most historic markets. Food tours are usually on foot, though you can also explore the Trastevere neighborhood with bike and Segway tours.
