If you plan to attend France’s mega flea market and street party known as the Braderie, think again. The city of Lille’s annual market, always set for the first weekend in September, has fallen victim to increased security concerns in the wake of recent terrorist attacks. With millions of attendees expected, authorities feared the event couldn’t be adequately protected.

In the present climate throughout much of Western Europe, it’s important to confirm the status of any large-scale event set for a venue in which crowd flows are hard to monitor or control. Be sure to check the website of the event organizer itself, as tourist bureaus or other sources may be unaware of changes.

It’s probably a good bet to take along as few belongings as possible; you might otherwise be slowed down by inspection of bags and backpacks.
