Le Fort occupies the east of Mons-en-Barœul, on the boundary with Villeneuve-d'Ascq. The district is organised around the rue de Normandie and the rue d'Alsace, with the rues de Flandre, de Lorraine, du Poitou, de Bretagne and d'Anjou, which bear the names of French provinces. The Fort de Mons station, on the avenue du Chancelier-Adenauer, links it to the metro.
The district takes its name from the Fort de Mons, built from 1878 to 1880 as part of the fortification system of General Séré de Rivières. The army sold it to the town in 1972; renovated, it was inaugurated in June 1984 and became a Maison Folie in 2004, housing the library, at 2 rue de Normandie, the music conservatory, the Le Trait d'Union performance hall and an exhibition room. Around it, the condominiums of the 1960-1970 period are part of the Nouveau Mons; apartment sales in the district take place outside the boundary of the priority urban neighbourhood.
Le Fort stands at 1 554 €/m², the most affordable price in Mons-en-Barœul, 16 % below the municipal average, with twelve apartment sales a year. It is down 4 % over five years and 13,0 % over twelve months, a change to be read with caution on such a small volume.
Le Fort is the entry point to the Mons-en-Barœul market, at 1 554 €/m², 16 % below the municipal average and 8 % below Europe. The district brings together condominiums from the 1960-1970 period, the Fort de Mons metro station and a cultural facility, the library and music conservatory housed in the fort. The buyer profile is that of first-time buyers on a tight budget, families who want the metro nearby and investors targeting the rental market. Three points to check. The 13,0 % fall over twelve months is mainly due to 2025, at 1 433 €/m² against 1 647 in 2024, and rests on twelve sales a year: the 2021 to 2024 series, stable at around 1 616 to 1 657 €/m², and the 4 % fall over five years give a more reliable reading. Sales in one building on the rue d'Alsace, wrongly located in the DVF data, are counted in the municipal price but not in the district price. Finally, as throughout the Nouveau Mons, the condition of the building, service charges and energy performance weigh heavily on value.
The average price in Le Fort is 1 554 €/m² for an apartment (actual DVF transactions, notarised sales), within a range of 1 327 to 1 742 €/m² depending on the building, the floor and the condition.
