About Festiv'M&G Flea Market Grigny
Grigny, southern suburb and home of the Grande Borne estate
Grigny is an Essonne commune of around 28,000 inhabitants, in the southern inner suburbs of Greater Paris, along RER D. Best known for its Grande Borne estate — designed in the 1960s–70s by architect Renée Gailhoustet, with its winding lanes, coloured squares, integrated sculptures and organic forms — it is a remarkable piece of 20th-century urban heritage. The commune is part of the Grand Paris Sud agglomeration and is undergoing major urban renewal.
The Festiv'M&G association organises a festive flea market each year on the Allée des Iris, gathering between 80 and 120 private sellers. The festive atmosphere — with music, activities and refreshments — gives this event a warm, convivial character. Free entry for visitors.
