Some flea markets only take place once or twice a year. Their rarity makes them highly sought-after events, where crowds flock to discover the treasures that vendors have put aside from one year to the next. It is not uncommon for these events, which sometimes last a few days, to gather up to 10,000 exhibitors, both professional and private, and millions of visitors. And a whole day is often not enough to do the whole tour. These flea markets, which can easily be described as “as rare as hen’s teeth”, are the ideal place to make beautiful discoveries and bring home treasures at a very good price. If there are any events to mark in your calendar, they are those.
