In the Land of Art and History "from Senlis to Ermenonville", enjoy a beautiful romantic stroll.

Class " Monument ", this English park owes its name to the famous philosopher Jean-Jacques Rousseau who stayed there for the last six weeks of his life. He died there in 1778 and was buried in Poplar Island. The park then became a place of literary pilgrimage.

First “landscape garden” throughout continental Europe, the Marquis René de Girardin created the park between 1766 and 1775, inspired by certain ideas of the “New Héloïse”, a novel by Rousseau published in 1761. “philosophical landscapes” are arranged in the way that a painter conceives his picture, and many poetic inscriptions are intended to make the walker think.


Spread over 62 ha, the Park was classified in 2019 as a "Sensitive Natural Area" because it is home to many environments (afforestation, meadow, river, pond, etc.), typical and sometimes rare flora as well as wildlife.

Departmental domain, the current fleet represents only part of the initial fleet, which is divided between three different owners: the western sector, called "the Desert", belongs to the Institut de France, and the northern sector belongs to the domain of the hotel-restaurant established at the Château d'Ermenonville. These two other sectors are only open to the public to a limited extent.
