A boulevard is a wide, tree-lined street that often features a central median or park area. These streets are designed for both vehicles and pedestrians, making them pleasant places to walk, bike, or enjoy outdoor activities. Boulevards are commonly found in urban areas and are often lined with shops, cafes, and restaurants, creating vibrant social spaces. Many famous cities, like Paris with its Champs-Élysées or Los Angeles with its Sunset Boulevard, showcase beautiful boulevards that attract tourists and locals alike. These streets often serve as important cultural and historical landmarks, reflecting the character and lifestyle of the city.
