Parc Montsouris

If you’re around the area, come here for a bit of greenery as Parc Montsouris is one of Paris’ green lungs. For the adventurous who’ve read the Da Vinci Code, pretend you’re being chased by some sort of religious institution (of your choice) and see if you can spot the medallions that mark where the old longitudinal meridian used to be (before, sadly, it was moved to Greenwich). You’ll find a fair bit of youth chilling around, as the park is close to a university student accommodation. Other than that, there’s nothing of note.
