The Treilles Domaine: a history of its construction


Purchase of the land by Anne Gruner Schlumberger, followed by the development and restoration of the first houses:

La Maison du Hangar (the hangar house): currently houses the administrative offices and the fire protection vehicles hangar

La Maison du gardien (the warden’s house) is fitted out in an old mas (typical provencal construction) which was restored in 1961; it is still the warden’s) house.

In one of his works, Virgil describes his own swimming pool set amid olive trees, an idea which seduced Anne Gruner Schlumberger’s imagination. In 1961, encouraged by her enthusiasm, Pierre Barbe therefore designed one. Soon afterwards, the Maison de la Piscine (swimming pool house) was built, in which many discussions occurred revolving around plans and projects.

Gisclard: this house bears the name of its previous owner. He had bought it in 1942 and lived in it on a regular basis until 1961. With much kindness, he sold it and the renovation began in 1963. Jean Schlumberger stayed there with his daughter during the summer of 1964. He would usually find a cool spot below the great mulberry tree in the adjoining Provençal style courtyard to read the latest works by Roger Martin du Gard.



Aurési: a name which harks back to the life years of its previous owner. The house walls are of an older time, whereas the stairs and terrace were added later. The house was set up and arranged in 1965.

Building of the Grande Maison (Main House): in a state of ruins, the traditional mas which was found there was demolished in 1964; cypress trees were planted that same year to protect against the wind and to shape the landscape. The construction of the house, which was to become a place where people could meet, play and listen to music began in 1965 and the interior design finished in 1968. It already housed a library. Today, a piano is set up in the conference room which occasionally serves as a concert hall, depending on various guests’ talents.

Renovation or construction of three other houses:

Moussu which, until quite recently, was used by the previous owner to stock his hay or cereal harvests and which was also used as shelter during the hunting season, was refurbished in 1965.

L’Ammonite, bought from a farmer of the Changers plateau in 1962, gave its name to a new house designed by Pierre Barbe and built in 1966.

La Maison des enfants et des jeux (the Children’s and Game’s House), later named the «Petite Maison» (Little House) and dedicated, since 2009, to housing the residence authors.



Construction of Barjeantane. Built to be Anne Gruner Schlumberger’s house and to hold her collection of works of art, it currently houses the Treilles Literary Studies Centre’s funds, the «Jean Schlumberger Centre».



The three last houses of Treilles designed by Pierre Barbe were built in collaboration with the painter Chouchanik Seferian :

The “Maison de Fonction” and the “Maison d’Amis” which often house the seminar organisers

L’Atelier (the studio) which is still to this day the residence and workplace of the painter.

The Grande Maison’s library was also enlarged over this period.



Yves Nioré, architecture consultant, restored a small cottage near the Grande Maison, which is known today as the Maison des Chênes (Oak House) and designed what was to become his living and working place : Le Pertus

Construction of the Maison de l’Informatique – today known as the Maison des Sondes (Probe House) and Lou Pra (designed by architect Patrick Vallet), under the direction of Chouchanik Seferian.



September: inauguration of one of Takis’ works of art, the Jardin des Sondes (Probe garden), built from real oil probes, eponymous to the house they surround



Planning out and construction of the sky observation area (cabanon du telescope-telescope cottage)



July: Registration of the Domaine des Treilles on the historical monuments additional registry.
