The bulk of the building is two massive wings built in the mid-seventeenth century, by order of owner Louis I Phélypeaux, Comte de Pontchartrain, who was elevated in nobility and in ministerial rank to Chancellor of France. Lake Pontchartrain in Louisiana was named after him as well as the historic Hotel Pontchartrain in New Orleans, as was Fort Pontchartrain du Détroit in Michigan (the site of modern-day Detroit) and Detroit's Hotel Pontchartrain.

The Jardin botanique de l'Institut National is a small botanical garden located within the campus of the Institut des sciences et industries du vivant et de l'environnement (AgroParisTech), formerly known as the Institut National Agronomique Paris-Grignon, on the Avenue Lucien Brétignières, Thiverval-Grignon, Yvelines, Île-de-France, France. It is closed to the public but may be visited by groups. The garden was established sometime before 1979 on a plot of land adjacent to the Arboretum de Grignon. Today it consists of 34 beds containing about 1,000 taxa with an emphasis on Graminae, Leguminosae, ornamental plants, and plants of limestone soils. The Association de l'arbre de fer was established in 2001 to protect and enhance the campus' natural environment, and in 2003 it began restoration and enlargement of the arboretum, as well as creation of a botanical trail and rehabilitation of the garden.

The Arboretum de Grignon (0.8 hectares) is an arboretum located within the campus of the Institut des sciences et industries du vivant et de l'environnement (AgroParisTech) on Avenue Lucien Brétignières, Thiverval-Grignon, Yvelines, Île-de-France, France. It is closed to the public but may be visited by groups. The arboretum was established in 1873 by Pierre Mouillefert, professor at Grignon, who published in 1896 a pamphlet describing the arboretum at that date; however, it was lost in 1940. The arboretum grew gradually over time, with the most recent plantings between 1976-1978. Various of the trees were labeled in 1975 by Mr. George Callen of the Arboretum de Chèvreloup, and in 1991 Mr. Augustin Scalbert created a map identifying almost all trees. At that time, the arboretum contained approximately 230 specimens (66% deciduous, 34% conifers). Unfortunately, the arboretum was heavily damaged in the storm of December 1999, which destroyed 23 trees and severely damaged 16. In response, the Association de l'arbre de fer was established in 2001 to protect and enhance the natural environment of the former Institut National Agronomique Paris-Grignon. In 2003 it began restoration and enlargement of the arboretum, as well as creation of a botanical trail and rehabilitation of the campus botanical garden. Today the arboretum contains about 125 tree species and varieties, including notable, mature specimens of Cedrus atlantica, Fagus sylvatica var. "Tortuosa", Ginkgo biloba, Gleditsia triacanthos, Parrotia persica, Pinus nigra subsp. laricio, Sophora japonica "pendula", and Zelkova carpinifolia.
