The major September flea market in one of the most beautiful villages in the Yvelines
The Montfort-l'Amaury Back-to-School Flea Market is a major event that brings together about 300 participants every September in the historic center of one of the most beautiful villages in the Yvelines. Organized by the festival committee, this major flea market takes advantage of the exceptional medieval setting of Montfort-l'Amaury.
Organized by the Montfort-l'Amaury festival committee, this major back-to-school flea market is one of the largest in the western Yvelines with about 300 participants each year. Set up in the historic village center, particularly on 3 rue Amaury, it benefits from a unique heritage setting.
Montfort-l'Amaury is a heritage gem of the southwestern Yvelines. An ancient medieval stronghold, it preserves the remains of its feudal castle, notably the famous Anne of Brittany tower. The Saint-Pierre church, a listed Historic Monument, has remarkable 16th-century stained-glass windows.
With about 300 participants, this flea market is one of the largest in the western Yvelines. This scale offers bargain hunters a wide variety of exhibitors and items: antique and vintage furniture, crockery, lamps, paintings, books, records, trinkets, clothes.
One of the great attractions of this flea market is its location in the historic heart of the village. The stalls spread out in the cobblestone streets, under the old facades.
The September flea market is the perfect opportunity to combine a day of bargain hunting with in-depth discovery of Montfort-l'Amaury and its surroundings.
