A working-class quarter with a flea market that runs every single morning of the year — free, early, and the least polished thing in central Brussels.
What it costs
Free to walk into. The Place du Jeu de Balle flea market runs every morning, all year — it is one of very few in Europe that never takes a day off.
What you pay is what you haggle to. Prices are higher at the weekend, when the market is bigger and busier; weekday mornings are cheaper and are when dealers buy.
When to go
Mornings — it winds down by early afternoon. Saturday and Sunday are the big days and the dearest. Rue Haute and Rue Blaes on either side are lined with junk shops and design dealers.
Getting there
A short walk down from the Sablon, or the free glass lift beside the Palace of Justice, which drops you straight into the quarter and is worth the ride on its own.

If you only have an hour
Get to the Jeu de Balle before nine, walk the market, then go up Rue Blaes looking in the junk shops. Ride the free glass lift back up to the Sablon at the end. That is the best free hour in Brussels.
What people get wrong
The Marolles is a real neighbourhood under real pressure, not a heritage attraction — the Marollien dialect is nearly gone and the shops change hands fast. Behave accordingly, and note that the Palace of Justice above it has been under scaffolding for so long that the scaffolding is itself a local joke.
