Paris is divided into 20 arrondissements, which are like neighborhoods or districts within the city. Each arrondissement has its own unique charm, history, and attractions. The arrondissements are arranged in a clockwise spiral, starting with the 1st arrondissement in the center of the city and spiraling out to the 20th arrondissement on the outskirts. The 1st arrondissement is home to iconic landmarks like the Louvre Museum and the Tuileries Gardens, while the 3rd and 4th arrondissements, known as the Marais, are known for their trendy boutiques, art galleries, and historic architecture. The 5th arrondissement, also known as the Latin Quarter, is famous for its lively atmosphere and the Sorbonne University. The 7th arrondissement is where you'll find the Eiffel Tower and the Champs de Mars, while the 16th arrondissement is known for its upscale residential areas and beautiful parks. Each arrondissement offers something different, whether it's historic landmarks, shopping, dining, or nightlife. Exploring the arrondissements is a great way to get a sense of the diversity and vibrancy of Paris.
