How did the name “Flea Market” come about?
According to Wikipedia: The original flea market is likely to be the Marché aux puces (Singwell: this means ‘market of fleas”) of Saint-Ouen, Seine-Saint-Denis, in the northern suburbs of Paris. It is a large, long-established outdoor bazaar, one of four in Paris. They earned their name from the flea-infested clothing and rags sold there. From the late 17th century, the makeshift open-air market in the town of Saint-Ouen began as temporary stalls and benches among the fields and market gardens where ragpickers exchanged their findings for a small sum.
