The square staircase of this traboule, from the 17th century, was renovated a few years ago and was listed as an historic monument. It was part of the Feuillants monastery. A well is in the middle of the courtyard with the staircase. To exit, it is possible to go out in the "rue des Feuillants" or to take a hallway leading to the "cours des Moirages" (the traboule is called double because it has two exits).
