Auderghem is famous for flea markets. The two most renown are la Grande Brocante d’Hermann-Debroux (the great Hermann-Debroux flea market) and la brocante du parking du Carrefour d’Auderghem (Auderghem junction flea market) that take place once a month.

These flea markets welcome visitors in a pleasant and relaxed atmosphere, which makes them particularly friendly to a younger and older audience. Smaller flea markets also await visitors once a month on the Place Pinoy, and on the Boulevard du Souverain. Expect to find pleasant neighborhood flea markets, not necessarily high-end antiques.
