The gates at the end of "ruelle des chapeliers" is open during the day. We should be able to use the path when creating itinerary.

It is open to the public between 7am and 8pm via Rue Gaston Tardif on one side and at 7 Rue de Saint-Malo on the other. Outside these hours, the entrance gates allow access only to residents of the Cité d'Aleth and those living on the alleyway.
