Nestled in the 4th arrondissement of Paris behind the Notre Dame Cathedral, Square de l’Île-de-France, with its lush garden is the ideal place to relax and spend a refreshing evening. The park is home to Memorial des Martyrs de la Deportation, devoted to the French people who were sent to concentration camps during World War II, making for a significant point of interest. Loaded with beautiful rose beds, the square is the perfect picnicking spot in the French capital.
