Mons occupies the north-east of the town, between the Seine and the airport. It was a village in its own right until 6 August 1817, the date of its merger with Athis: the town as it stands still carries both names.
The district is laid out around the rue d'Ablon, the rue Robert-Schuman, the avenue de l'Europe and the rue de la Montagne-de-Mons, which climbs from the river towards the plateau. The housing stock mixes old village houses, twentieth-century detached houses and small developments. To the north, the area touches the grounds of Paris-Orly airport, which take up 13,6 % of the town's territory.
On the market, Mons sits at around 3 371 €/m² for an apartment, on only about 10 sales a year. The range there is wide, from 2 434 to 3 567 €/m². The district gains 8,8 % over twelve months, but at that level of volume the trend has to be read with caution.
Mons attracts buyers who care about the setting: the banks of the Seine, the Montagne de Mons and the village character kept by the old streets. Ablon station, on the RER C, is within reach. The market there is narrow, with few apartments and a majority of houses, which makes every sale decisive in the district average. Exposure to aircraft noise weighs in negotiations in the northern part.
