Jardin Atlantique
Built above the tracks of Gare Montparnasse, this park nestled among tall modern buildings is named for its assortment of trees and plants typically found in coastal regions near the Atlantic Ocean. In the center of the park, what looks like a quirky piece of metallic sculpture is actually a meteorological center, with a battery of flickering lights reflecting temperature, wind speed, and monthly rainfall. It's not really worth a detour, but it's a good green space if you're already nearby.
