The "City Beautiful" movement emerged in the late 19th and early 20th centuries in the United States. It aimed to improve urban environments through the incorporation of beautification and monumental architecture. Advocates believed that aesthetically pleasing cities would promote civic pride and social order, leading to improved quality of life for residents. Key features of the movement included the design of parks, grand boulevards, and public spaces, often inspired by classical architecture. Notable examples include the Chicago World's Fair of 1893 and the McMillan Plan for Washington, D.C.. The movement significantly influenced urban planning and landscape architecture in America.
