Beautification is the process of making visual improvements to a person, place, or thing. With regard 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.
