St. Honor and the Palais Royal
Description:
The map shown here is a section of the 1705 "Huitième plan de Paris divisé en ses vingts quartiers" by Nicolas de Fer. It shows several locales that show up in la Maupin's story.

Just south of the letter "Q" on the left side of the picture is the "manège de grande écurie"—the armory of the Great Stable—which the comte d'Armagnac was in charge of.
In the middle of the top half of the image is the Palais Royal itself. At the southeast or lower left corner of the palace is the label "l'Opera", which presumably marks the location of the Théâtre du Palais-Royal, though modern maps take you to the northwest corner of the palace.
To the south of the palace the Rue St. Thomas du Louvre, where la Maupin fought her duel with the three gentlemen who took exception to her propositioning the young lady at Monsieur's ball. West of the Palace, running diagonally, is the Rue Traversière (referred to as the "Rue Traversière-Saint-Honoré" to distinguish it) where la Maupin rented her lodging from M. Langlois, and is said to have attacked the cook with the key.
Northeast of the palace in the upper right of the picture, is the Place des Victoires, where she confronted Desmenil and caned him when he would not draw swords with her. This suggests that his home was further to the northeast, perhaps somewhere in le Marais ("the Marsh"), a neighborhood favored by much of the aristocracy. The comte d'Armagnac is also said to have lived in le Marais.
