A large double door and a semicircular arch lead inside from the street. An independent staircase situated in the center of the facade, leads up the apartment rented by Delacroix, who had exclusive use of the small, enclosed garden (approximately five hundred square meters).
These buildings probably date from the very late seventeenth century, when Cardinal Egon de Furstenberg was renovating the abbatial palace. They were probably among the outbuildings, which would explain the mediocre quality of the construction and the fact that the façades were not faced.
A detailed history of these buildings, both in terms of architecture and history, has not yet been undertaken.
