Neolithic "Neolithic") times. Agriculture was developed, notably during the [Roman](/wiki/Roman_Empire "Roman Empire") era. Between the 12th and the 18th century, an important Benedictine abbey was housed in Gif. In the 19th century, amid the [Industrial Revolution](/wiki/Industrial_Revolution "Industrial Revolution"), Gif remained largely agricultural, with operating mills in particular.

Château de Button

In the 1770s, the Château de Button by architect Pierre Desmaisons was completed in Gif. In 1946, the [French National Centre for Scientific Research](/wiki/French_National_Centre_for_Scientific_Research "French National Centre for Scientific Research") (CNRS) installed an office and research facility on the property.[[3]](#cite_note-3)

In 1867, the town was linked to Paris by train with the [Ligne de Sceaux](/wiki/Ligne_de_Sceaux "Ligne de Sceaux") in the valley, which would later become the southern branch of the current-day [RER B](/wiki/RER_B "RER B") line.

Église Saint-Rémi in Gif-sur-Yvette

Following the [First World War](/wiki/World_War_I "World War I"), the Gif commune experienced an important demographic change, with an increasing population. The town took the name of Gif-sur-Yvette in 1930.

Just after the [Second World War](/wiki/World_War_II "World War II"), Gif-sur-Yvette acquired an international scientific reputation, with the CNRS and [Atomic Energy Commission](/wiki/French_Alternative_Energies_and_Atomic_Energy_Commission "French Alternative Energies and Atomic Energy Commission") (CEA) moving there. The CEA discovered [radioactive contamination](/wiki/Radioactive_contamination "Radioactive contamination") in a private home in Gif-sur-Yvette in 1974; the home had been built upon a site where needles containing [radon](/wiki/Radon "Radon") gas were once manufactured,[[4]](#cite_note-4) starting in 1915. The needles were used to sterilise infected tissue—an idea developed by [Marie Curie](/wiki/Marie_Curie "Marie Curie").

The town was extended in 1975, with the creation of the Chevry neighbourhood, from areas ceded by the [Gometz-la-Ville](/wiki/Gometz-la-Ville "Gometz-la-Ville") and [Gometz-le-Châtel](/wiki/Gometz-le-Ch%C3%A2tel "Gometz-le-Châtel") communes.

The Église Saint-Rémi (Saint Rémi church), a structure of [Romanesque](/wiki/Romanesque_architecture "Romanesque architecture") and [Gothic architecture](/wiki/Gothic_architecture "Gothic architecture"), was built in the 12th century. It was registered as a [historic monument](/wiki/Monument_historique "Monument historique") in 1938.[[5]](#cite_note-5)

Some ruins remain of a [Benedictine](/wiki/Benedictines "Benedictines") [abbey](/wiki/Abbey "Abbey") which was built in the 12th century and became a national property in 1789 amid the [French Revolution](/wiki/French_Revolution "French Revolution"). It was officially registered in 1963.[*[citation needed](/wiki/Wikipedia:Citation_needed "Wikipedia:Citation needed")*]

Inhabitants of Gif-sur-Yvette are known as *Giffois* (masculine) and *Giffoises* (feminine) in French.

**Paris-Saclay** is a [research-intensive](/wiki/Research-intensive_cluster "Research-intensive cluster") and [business cluster](/wiki/Business_cluster "Business cluster") currently under construction in the south of Paris, France. It encompasses research facilities, two French major universities with higher education institutions (*[grandes écoles](/wiki/Grandes_%C3%A9coles "Grandes écoles")*) and also research centers of private companies. In 2013, the [Technology Review](/wiki/Technology_Review "Technology Review") put Paris-Saclay in the top 8 world research clusters.[[4]](#cite_note-4) In 2014, it comprised almost 15% of French scientific research capacity.

The earliest settlements are from the 1950s, and this area was subsequently extended several times during the 1970s and 2000s. Several projects are underway to continue the development of the campus, including the relocation of some facilities.

The area is now home to many of the Europe's largest [high-tech corporations](/wiki/Technology_company "Technology company"), and to the two French universities [Paris-Saclay University](/wiki/Paris-Saclay_University "Paris-Saclay University") ([CentraleSupélec](/wiki/CentraleSup%C3%A9lec "CentraleSupélec"), [ENS Paris-Saclay](/wiki/%C3%89cole_normale_sup%C3%A9rieure_Paris-Saclay "École normale supérieure Paris-Saclay"), [Paris-Saclay Faculty of Science](/wiki/Paris-Saclay_Faculty_of_Sciences "Paris-Saclay Faculty of Sciences"), etc.) and the [Polytechnic Institute of Paris](/wiki/Polytechnic_Institute_of_Paris "Polytechnic Institute of Paris") (*[École Polytechnique](/wiki/%C3%89cole_Polytechnique "École Polytechnique")*, [Telecom Paris](/wiki/Telecom_Paris "Telecom Paris"), etc.). The [Paris-Saclay University](/wiki/Paris-Saclay_University "Paris-Saclay University") was ranked 15th in the world in the 2023 [ARWU](/wiki/Academic_Ranking_of_World_Universities "Academic Ranking of World Universities") ranking. It was also placed 1st in the world for [Mathematics](/wiki/Paris-Saclay_Faculty_of_Sciences "Paris-Saclay Faculty of Sciences") and 9th in the world for [Physics](/wiki/Paris-Saclay_Faculty_of_Sciences "Paris-Saclay Faculty of Sciences") (1st in Europe).[[5]](#cite_note-5)

The goal was to strengthen the cluster to build an international scientific and technological hub that can compete with other high-technology business districts, such as [Silicon Valley](/wiki/Silicon_Valley "Silicon Valley") or [Cambridge, MA](/wiki/Cambridge,_MA "Cambridge, MA"). This project started in 2006 and is likely to end in 2022. The main part is the construction of the *campus du [plateau de Saclay](/wiki/Plateau_de_Saclay "Plateau de Saclay")
