La Fontaine Médicis might be the most romantic fountain in all of Paris -- and it's also one of the original remaining decorations of Queen Marie de Medicis. Located in the Luxembourg Gardens, it was built in the 1630's for the queen so she could reminisce about her childhood grotto in Florence, Italy in the Boboli Gardens. Find a chair underneath the big shady plane trees and just breathe. This is a spot of pure peacefulness and romance for the young at heart!
