Marché d’Aligre is a market that opened in the 18th century and hasn’t changed a lot since then. It consists of two parts: the open-air flea market and the Marché Beauveau – a covered part with dairy products, seafood, poultry and much more. Apart from the antiques and vintage stuff, d’Aligre also contains some nice eateries of various cuisines.
Things to look out for in Paris are regular brocante fairs. These are open-air flea markets where vendors offer antiques, knick-knacks and all manner of second-hand goods. In the summer they can be organised as often as every week in various parts of the city.
