The garden and the "Turret"

The Museum conjures up an evocation of the little Mont-Louis. In the garden, the "study out of greenery" and the "Turret", have been rehabilitated.

"When I was there I amused myself by adorning the terrace which was already shaded by two rows of young lime trees- I had two more added to them to make a study out of greenery- I had a table and stone benches put there- I surrounded it with lilacs, syringa, honeysuckle."

"This Turret, which ended a terraced path, opened onto the valley and pond of Montmorency It was in this place that I composed my Letter to d'Alembert on the Theater."
