In 1115, legend has it that Seneschal Anseau de
Garlande and his niece Yolande cross the forest of Roissy-en-Brie on
horseback when a boar attacks his niece's mount. It was then that a
peasant from Torcy and a peasant from Roissy-en-Brie rushed to help
the lord and the young lady. To reward this act of bravery, Anseau
de Garlande therefore offered a parcel of forest, about 150
hectares, to the villages of Torcy and Roissy-en-Brie, the forest
being a wealth at the time because it was a game reserve. and wood
for construction and heating.
There was a priory at Roissy which was in ruins in the 19th century. During this period, gypsum was extracted and tillage implements were made there.
The Château de Roissy, which currently houses the town hall, dates from the 17th century. Its beauty has attracted many illustrious characters such as the great singer Maria Malibran, Dr Photinos Panas, eminent ophthalmologist of the last century or even Charles Pathé, the greatest industrialist of cinema, who receives the greatest stars of the seventh art at the château.
Roissy absorbed the municipality of Pontcarré in 1810 and separated from it in 1829, thus returning it to its status as a municipality.
Since 1970, the city has grown rapidly, going from 500 to nearly 23,000 inhabitants in 2017. The immense wheat fields have given way to residential and real estate complexes, although the woods still represent 50% of the municipal territory.
In order to achieve the good water status imposed by the Water Framework Directive of 23 October 2000, several integrated management tools are articulated at different scales: the SDAGE, at the hydrographic basin scale, and the SAGE , at the local level. The latter sets the general objectives of use, development and quantitative and qualitative protection of surface and underground water resources. The Seine-et-Marne department is covered by six SAGEs, within the Seine-Normandy basin6. The town is part of two SAGE: "Yerres" and "Marne Confluence".
The SAGE “Yerres” was approved on October 13, 2011. It corresponds to the Yerres watershed, with an area of 1,017 km2, traversed by a hydrographic network of approximately 450 kilometers in length, divided between the course of the river. 'Yerres and its main tributaries which are: the Ru de l'Étang de Beuvron, the Visandre, the Yvron, the Bréon, the Avon, the Marsange, the Barbançonne, the Réveillon7. SAGE is managed and coordinated by the joint union for sanitation and water management in the Yerres watershed (SYAGE), described as a "supporting structure".
The SAGE “Marne Confluence” was approved on January 2, 2018. It covers the downstream part of the Marne watershed straddling the departments of Seine-et-Marne, Seine-Saint-Denis and Val-de-Marne . In total, 52 municipalities are concerned, covering an area of 270 km. SAGE is managed and coordinated by the Marne Vive union, described as a "supporting structure", a mixed union created in 199310.
The town benefits from a "degraded oceanic climate of the plains of the Center and North", according to the typology of climates in France defined in 2010. This type affects the entire Paris Basin with an extension towards the south, including all of the municipalities of Seine-et-Marne.
The climatic parameters which made it possible to establish this typology include six variables for temperature and eight for precipitation, the values of which correspond to the monthly data for the 1971-2000 normal. The seven main variables characterizing the municipality are presented in the box opposite. With climate change, these variables have since evolved. A study carried out in 2014 by the Directorate General for Energy and Climate in fact predicts that the average temperature should increase and the average rainfall fall, with however strong regional variations. This development can be seen on the nearest historic Météo-France meteorological station, Melun - Villaroche, which is 20 km away as the crow flies, where the annual average temperature is 11.2 ° C for 1981-201015 at 11.6 ° C for 1991-2020.
Natural environments and biodiversity
The inventory of natural areas of ecological, faunistic and floristic interest (ZNIEFF) aims to cover the most interesting areas from an ecological point of view, essentially with a view to improving knowledge of the national natural heritage and providing a tool to help the various decision-makers take the environment into account in regional planning.
Administrative and electoral attachments
The town has been located since 1994 in the district of Torcy in the department of Seine-et-Marne. For the election of deputies, it has been part of the eighth district of Seine-et-Marne since 1988.

Roissy-en-Brie and Pontault-Combault. came together on January 1, 2010 to form the agglomeration community of Brie Francilienne.
As part of the implementation of the MAPAM law of January 27, 2014, which provides for the generalization of intercommunality to all municipalities and the creation of large-scale intercommunalities in Île-de-France, capable of dialogue with the metropolis of Greater Paris, this intercommunal merger with its neighbors to form, on January 1, 2016, the Paris - Marne Valley urban community, of which the municipality is now a member.
