The biggest one is held on Thursdays and Saturdays and is aptly named Feira da Ladra (thieve’s market) in the neighborhood of Alfama, accessible by the Tram 28. The market starts at the Arco de São Vicente and continues well behind the Santa Engracia Church. Feira da Ladra offers everything from 16th-century tiles to mobile phone chargers. Haggling is not only welcome, it’s expected.
Another great flea market happens twice a month in the neighborhood of Belém in front of the Mosteiro dos Jerónimos. Vendors here sell antiques, books, and tourist trinkets. A great place for good-quality used cameras. The market extends into the modern courtyard of the Centro Cultural de Belém, where it becomes much craftier, snazzier, and more in line with what your typical hipster family would expect from their Sunday shopping: artisanal edibles, locally made wearables, quirky “original” home goods, hand-made soaps, and a good selection of honey. It’s quite good.
