First I noticed the door, with a text above it. IOAN REBOVL Vixit et obhit, it said, and I had no clue who Ioan Rebovl might have been.
At home I learned the following. Ioan Rebovl means Jean Reboul (1796–1864), who was a famous baker and a poet from Nîmes. The building in the picture is the place of his birth, and later also of his bakery, where he worked until his death. The street is nowadays named after the poet, known especially of his work L’Ange et l’enfant (1928), as Rue Jean Reboul.
In the Jardins de la Fontaine there’s also Jean Reboul’s statue, I’ll have to take a picture of it one day. More on Jean Reboul here (in French).
