Narrow streets are typically found in older urban areas where buildings were constructed close together. These streets often limit vehicle access and can create a more pedestrian-friendly environment. They may feature cobblestones or brick paving, adding to their charm and historical significance. In many cities, narrow streets are lined with small shops, cafes, and homes, fostering a sense of community. They can also pose challenges for emergency services and traffic flow. Examples of cities with narrow streets include Venice, Paris, and Barcelona, where such streets contribute to the unique character and atmosphere of the area.
