The Château de Grignon stands in Thiverval-Grignon, in the Yvelines department, and dates from the 17th century. It passed through several noble families linked to the Parliament of Paris before becoming, from 1826 onward, the seat of an agricultural school that later became AgroParisTech. The building reflects this dual history, first a seigneurial residence, then a center of agronomic education, and its grounds housed generations of engineering students.
