The project shows a building with a main vaulted nave, punctuated a circular main hall topped with a dome decorated with festoons, pedestals and figures of angels, serving several side chapels, and finally a vaulted room.
The façade with portico and pediment, on the back a semicircular colonnade under a lowered dome.
Although no distinctive religious sign is visible on the design, layout and decoration of the building by figures of angels and statues in niches leaves little doubt about the ecclesial character of the building.
Comparable to the works of Renard, de Bourge, Maréchaux, and in general the students of the Paris Academy of Architecture in the early 1770s.

The old mount was preserved, the drawing being pasted on cardboard, surrounded by a pleasant light green passe-partout.
Fine preservation. Some stains, slightly insolated.
