Marcel Proust used to laze under the trees in this beautiful park, and who could blame him? The lush lawns and leafy trees of this verdant haven would brighten the spirits of even the most melancholy writer. Located in a posh residential neighborhood and ringed by stately mansions, this small park, commissioned by the duke of Chartres in 1769, is filled with folies, faux romantic ruins, temples, and antiquities inspired by exotic faraway places. Don’t be surprised to stumble upon a minaret, a windmill, or a mini-Egyptian pyramid here. The most famous folie is the Naumachie, a large oval pond surrounded in part by Corinthian columns. You’ll find a sizeable playground in the southwest corner, as well as a merry-go-round near the north entrance.
