The nuns' private chapel

In 1646, a letter of patent from Louis XIV authorised the construction of a chapel for the Office of the Disabled Poor. Inaugurated in 1651, it was a medium-sized building of about 80 m2, with a wooden framework, built from existing buildings and located on the edge of the present Rue de Germont, where its entrance, known as the "Porte des Dames", is located. It was first run by nuns from the Congregation of the Daughters of the Cross before being replaced in 1714 by nuns from the Congregation of Notre Dame de Charité, founded the same year. It has two separate galleries for men and women, as it also welcomes the public. The level of the ground floor is slightly lower than that of the street, making the church damp. Threatening to collapse and becoming dangerous, it was destroyed in 1849 and replaced by a new private chapel, located on the ground floor of a new building built in the rue de Germont the same year, practically on the site of the old one, but on the courtyard side.

Of this private chapel, which was inaugurated in 1855 by the Archbishop of Rouen, all that remains are the two round stone entrance columns which now serve as access to the dermatology department.
