Saint-Nom-la-Bretèche was built around 4 core hamlets near the Forest of Marly. The village takes its name from a 9th-century co-bishop, saint Nonne, who re-evangelized the country after the Norman invasions, and from La Bretesche, a wooden stronghold (from breit eiche: big oak tree) consisting of a hamlet at the edge of the forest of Cruye, now the forest of Marly.
The hamlet was originally called "Saint-Nonne au Val de Galie", the name of the parish, then "Saint-Nom près de la Bretesche" and since the Revolution, "Saint-Nom-la-Bretèche".
During the French Revolution the district was called "La Montagne Fromentale" and then "l'Union la Bretesche".
The hamlets of Avinières, Val-Martin, La Tuilerie-Bignon were the responsibility of numerous lords, as well as of the Dames de Poissy and the Vaux-de-Cernay Abbey.
The north of the village, La Bretèche, was part of Marly Park, while the south, Saint-Nom, was part of Versailles Park [fr], making it difficult for the village as a whole to acquire an identity well into the 20th century.
Steady demographic growth, which accelerated significantly after 1982, eventually unified the two villages and allowed the building of a "Centre Village" and a Library by 2000.
Some historic structures in the village suffered irreparable damage from a freak storm with tornado strength winds that struck France in December 1999. The storm, which also damaged nearby Versailles, uprooted centuries-old trees and part of the wall of the Château de la Bretèche along the Route de Sainte Gemme.
Saint Nom is known internationally for its golf course in the Tuilerie area.
History
In 1954, Mr. Ortet, owner of the "Ferme de le Tuilerie", asked a real estate agent, Daniel Feau, to find a potential buyer for his property. Feau wanted to build a large golf course in the Paris area.
On May 2, 1957, Mr. Entem, mayor of the village, officially revealed the project of a golf course to the town council.
1959 saw the opening of a 36-hole golf course.
Origin of the Trophée Lancôme
Saint-Nom resident Gaëtan Mourgue D'Algue wanted to popularize the then little-known sport of Golf in France. With Dominique Motte, he suggested the creation of a new "champion-trophy" to Pierre Menet, the chairman of the Lancôme Company, whose goal would be to bring together eight of the best players in the world.
The Canada Cup, took place in Saint-Nom-La-Bretèche in 1963, which enhanced the village's international reputation.
The first 54-hole competition took place in 1970 and was won by Tony Jacklin.
The Ferme de Saint-Nom, given by a lord of Poissy to the Vaux de Cernay monastery in 1228, and profited from numerous donations. By incrementally and regularly gaining plots of land, the cistercian monks turned the agricultural estate into what was then considered to be a model farm, setting well distributed buildings around a farmyard. Sold as public property during the French Revolution, the farm was greatly modified during the 17th and 18th centuries. In the 20th century, lodgings were established on the property; the only remaining memento of the original farm was the inscription of its name, written over the porchway.
The Ferme de Valmartin belonged to a seigniory until 1600, when it was sold to the nuns of the Royal convent of the Dames de Poissy. It was transformed into a farm by the end of the 18th century, where it was used to breed merino sheep. The farm was sold as public property during the French Revolution.
Tuilerie-Bignon
Formerly part of Versailles Park, this land was later turned into Saint-Nom's prestigious golf course.
Church of Saint Nom
The church was originally a tithe barn belonging to the Ferme de St-Nom. A watchtower was erected to protect the church in the 12th century. The church has been expanded, partially destroyed and remodeled between the 12th and 20th centuries. It was restored in the late 20th century.
Forêt de Marly
The Forêt de Marly is an ancient oak forest formerly called the Forêt de Cruye. It covers one third of Saint-Nom.
The coat of arms of Saint-Nom shows in its center the "fasce bretessée" which evokes the etymology of Bretèche (from the Latin bretachiae): a fortification built at the entrance of a forest.
