Jeu de Balles is a quintessential flea market set in the heart of the Marolles District of Brussels that runs daily through the morning. My favorite time to go is on Sunday when the square is filled with the most vendors who sell anything from bric-a-brac to antique furniture. Since it is one of the city's most well-known markets, it's not always easy to find steals, but you can still manage to haggle a decent bargain. One of my favorite finds was a dealer who specialized in vintage, ceramic figurines full of quirk and character.
