19 Best Paris Walking Tours | Condé Nast Traveler

"Square René-Viviani is a charming and intimate garden (named for a former Prime Minister of France), offering spectacular views of the nearby Notre Dame Cathedral. The star of the square is the oldest living tree in Paris, a black locust, said to have been planted in 1601 by Jean Robin, who was the herbalist and gardener to Henri III, Henri IV, and Louis XII. There is also a fountain, created by artist Georges Jeanclos, that tells the story of St. Julien but also stands to commemorate the Jewish children killed during the Vichy regime." - Melissa Liebling-Goldberg
