The 2026 edition of the Lille Flea Market, held over the weekend of September 5 and 6, drew more than 2.5 million visitors, solidifying its position as Europe's largest flea market. The event spanned 53 kilometers of stalls, featuring 5,425 exhibitors. These included 2,769 stands set up by local residents, 1,877 stores, and 514 antique dealers and flea market vendors. At Saint-Sauveur Station, the Children's Flea Market also saw strong turnout, with all 90 stands sold and nearly 18,500 visitors welcomed over the two days. To ensure smooth operations, over 600 city agents were deployed to manage logistics, computing, and communication. An "anti-jam" system was activated seven times to regulate pedestrian movement in eight high-traffic areas. Security was handled by 145 municipal police officers, supported by 72 video surveillance cameras monitored by the Urban Supervision Center (CSU), 16 emergency posts, 640 concrete blocks, and 1,571 barriers to control visitor flows and maintain order. The event generated significant waste, with approximately 384 tons collected, including 560 kg of organic waste, 6,980 kg of cardboard, and 2,140 kg of glass. This waste was managed through a selective sorting system specifically set up for the occasion, promoting recycling and reducing environmental impact. On Monday, September 7, the City of Lille, in partnership with the Linkee association and the restaurant La Chicorée, held the third consecutive solidarity meal. Using unsold food from the Flea Market, they prepared and served 1,000 meals to people in precarious situations, including over a ton of mussels and about 500 kg of fries. The City of Lille expressed its satisfaction with the event's success and extended its gratitude to all participants and contributors. The flea market not only serves as a major economic and cultural event but also highlights the city's commitment to community support and environmental responsibility.
