"Chapel dedicated to Saint Firmin. It stands on the site of an original chapel and was built in 1580. It includes a second section known as the "ladies' choir," which was rebuilt between 1707 and 1709. It is still enclosed today by a fence and well-preserved small-frame doors.
The chapel is built of flint, with white stone buttresses. The pointed windows indicate the 16th century. Major renovations in the 18th century profoundly transformed it; the two slate-clad bell towers and the ladies' choir (1707) date from this period. In 1730, the chapel was considered in very poor condition and ready to collapse, and access was prohibited.
The west gable wall adjoins another building. The main entrance is on the north wall. The portal is framed by a semicircular arch.
The north drip wall is punctuated by five buttresses and pierced by four rectangular bays, one with a semicircular arch and the others with pointed arches. The south drip wall has a similar layout with rectangular bays and a door in the western part of the building.
The entire building is saddle-roofed. A hexagonal bell tower is placed like a stool on the western ridge of the church.
The chapel is home to, among others, Gabrielle Orieult, known as Saint Melaine, founder of the hospital in 1669.
The chapel organ was donated to the hospice by Pierre Henry-Lavaux in 1711. Abandoned in 1789, it was restored in 1823 following the actions of Fallouard. It was also restored in 1993. Today, following the theft of the pipes, only the remarkable organ case is visible.
Since 2004, the Racines de Honfleur association has been responsible for its preservation and restoration."
