Fictional alleyways are often interwoven between the more central roads and streets of fictional towns and cities, creating a network of narrow corridors that connect distant locations. When designing alleyways, a sense of enclosure is important. This is often accomplished through the use of tall buildings, narrow streets, and overhanging awnings, bridges, and other structures. This lends itself to either a claustrophobic feel, or if the world is more optimistic, can be used to foster a sense of coziness. Fictional alleyways are also often arranged like a labyrinthian maze.
