Location: The Sunday market stretches into "Le Miroir" on rue Léopold I (between chaussée de Jette and boulevard de Smet de Naeyer), as well as rue Pierre Timmermans and avenue de Jette (between avenue de Laeken and rue Prince Baudouin and rue Leon Dopéré), plus on the central berm of Jette and the beginning of chaussée de Wemmel.

Enjoyable large market where you can get just about anything. Imaginative parking skills required. Photo taken from Le Miroir.

Place de la Monnaie

Weekly organic market
Wednesday : 9am - 2pm

Now held at place Sainte Catherine (on the same time and day).
There were only 5 vendors when I visited but they did stock all the essentials.

Daily market (advertised as a full market on Saturdays)
Everyday : 7am - 1pm

Place du Châtelain

Weekly market
Wednesday : 1pm - 7.30pm
Location: between rue de l'Aqueduc and rue Simonis

Very pleasing compact market. After work it's busy and social: "the place to be seen". Cheese man from place St. Job and Italian vendor also at Chaussée de Boondael. Difficult for parking.

Chaussée d'Anvers

Weekly market
Wednesday : 7am - 1pm
Location: between rue Masui and Square Jules De Trooz

Place Sainte-Catherine

Daily market
Everyday : 7am - 5pm

This market is meant to be on every day but there are few regular stalls. The best day is the Wednesday organic market. In 2008, the city moved the organic market from place de la Monnaie to this location. However, a stall selling a large variety of potatoes and some onions, an oyster stand (pictured) and a cheese/charcuterie vendor also appear irregularly. Some days there are none.

Rue au Beurre Portraits

Art market - paintings and portraits
Everyday : 11am - 6pm
Location: between the Grand Place and the Bourse - the little street with the fountain.

Over winter I looked for this market on a Tuesday, Wednesday, Friday and Saturday but it was no where to be seen... In late Spring, as the tourist season began, a portraitist and a characaturist appeared.

Place du Jeu de Balle Brocante

Flea market of secondhand items.
Everyday : 7am - 2pm
Location: quartier Les Marolles on rue Blaes between rue du Chevreuil and rue de l'Hectolitre.

This place is always popular. Lots of junk. Photo taken on a Tuesday. The Friday evening food market I have found advertised does not take place.

Since 2006, to celebrate Tintin's visit to this market in 'Le Secret de la Licorne' a special Tintin day is held on the Saturday nearest the Belgian national holiday (21 July) -- scheduled for the 19th in 2008.

Grand Place Flower Market

Flower and plant market
Everyday except Monday and Thursday : 8am - 6pm

Sadly, the bird market seems to have gone the way of the Dodo. Quite small with the addition of vendors of tourist sketches and watercolours.
