The 1st Arrondissement is the center of the old city of Paris and home to many beautiful historic buildings, The Louvre Museum, the adjacent Jardins des Tuileries and The Place de la Concorde.
2nd Arrondissement is located near the city center, on the right bank of the Seine, not far from the Louvre and Tuileries gardens.
Just like the 2nd Arrondissement, the 3rd Arrondissement is located near the heart of Paris but luckily for you, also forgotten by tourists.
The Marais neighborhood that spills from the 3rd Arrondissement into the 4th arrondissement, contains the Place des Vosges, known as the most beautiful square in Europe.
