The Cour du Mûrier:

In the cloister of the old convent, Alexandre Lenoir planted a Chinese mulberry tree (mûrier), which gave its name to this shady courtyard. Duban rebuilt the cloister in 1836, transforming it into a Classical atrium surrounded with arcades and decorated with a fountain. During the Second Empire he completed the decoration with paintings in the style of Pompeii and casts of the Pantheon friezes, which are displayed half-way up the walls on three sides of the courtyard.
