Such objects include landscapes, sunsets, humans and works of art. Beauty, art and taste are the main subjects of aesthetics, one of the fields of study within philosophy.

Beautification is the process of making visual improvements to a town, city, or urban area. This most often involves planting trees, shrubbery, and other greenery, but frequently also includes adding decorative or historic-style street lights and other lighting and replacing broken pavement, often with brick or other natural materials. Old-fashioned cobblestones are sometimes used for crosswalks; they provide the additional benefit of slowing motorists.
