We visited the largest flea market in Europe, Braderie de Lille, which is held once a year for two days in Lille. We booked a room in the super beautiful mansion with the best spot: l’Esplanade. Just in front of the flea market. On that market you will find fantastic vintage stuff. Worth a visit! Finish your day by eating mussels at Aux Moules. At the end of each day there will be a large mountain of empty mussel shells next to the restaurant. A good indication of how many people love to eat mussels at Aux Moules!
