I have already made number of posts on the Philippe-Auguste Wall, built 1190-1210, which once surrounded a much smaller Paris. If you click here you can also find the previous posts.
A tower of this wall has recently been restored, made visible. You can now visit it in a little garden, also refitted and embellished in the Marais area - "Jardin des Rosiers-Joseph Migneret". It’s not obvious to find it – you can enter via 10, Rue des Rosiers (see previous post) or via 35-37, Rue des Francs-Bourgeois (see previous post).
One has obviously been forced to make an opening in the wall to enable the entrance to the little garden.
I would like to draw your attention to the chimney. My next post will talk about this chimney.
