Taking the title as the oldest covered market (over 400 years old!) in Paris, Marché des Enfants Rouges gets it’s name from it’s previous resident, an orphanage where the children were dressed in red, the color of the Christian charity during that time.
Today, this is a diner's (and food shoppers) paradise. Weekday lunch and weekend brunch can be extremely hectic at the market, so take this chance to stroll around before the hungry crowds roll through. You can find everything from, “Paris’ best sandwich” to Moroccan couscous; to freshly picked flowers and sensational french cheese. Feel free to nibble here and there, and pick up some snacks for later, but don't get too full because lunch is on the way.
