Engulfing the Porte de Clignancourt area at the northern edge of the city, this claims to be the largest antiques market in the world. Split into 15 specialty markets, thousands of visitors descend on this sprawling mini-city each weekend (also open Mon). Once a bargain-hunter’s dream, prices now often rival those of regular antiques dealers. Still, hard-core browsers will get a kick wandering through the serpentine alleyways of this Parisian medina, and may turn up a treasure. Note: Beware of pickpockets. Also to avoid the tatty markets surrounding Les Puces, get off at Métro Garibaldi.
