Solution

Read the first riddle.

Usually, the riddle begins with more general information (a street name), and moves towards the most specific (a place, a building, a monument, a detail).

When you approach the location, if you can't find it, reread the text to remember the details.

The map will be useful to you, because it is drawn expressly for the treasure hunt.

The answer to the first question is Batterie Dauphine. It is located outside on a plaque near the entrance to the Auberge Saint-Antoine on rue Saint-Antoine.
