Every city is a complex environment, bringing together people, cultures, architecture, commerce, and even nature. While experiencing a city, a lot of attention is given to its appearance, but appearance is not everything. The theory of sensory design aims to go beyond vision and explore the richness of the built environment through textures, smells, and sounds. For city officials and planners, a lot of attention generally goes towards how a city looks and sounds, but in terms of smell, the focus is mainly on managing waste or cleaning unsanitary areas. Yet the sense of smell, so often overlooked, is strongly linked to the creation of emotional memories. It contributes to our understanding of the world; it reveals otherwise hidden cultural practices, and it rounds up the experience of an environment.
