Which city was designed incorporating the principles of the City Beautiful?

The city designed incorporating the principles of the City Beautiful movement is Chicago. The City Beautiful movement emerged in the late 19th and early 20th centuries, advocating for urban planning that emphasizes beauty and aesthetic design as a way to foster civic virtue and improve the quality of life. Chicago was a central hub for this movement, especially in the wake of the 1893 World's Columbian Exposition, which showcased architectural grandeur and urban planning ideals.

The City Beautiful movement in Chicago led to significant urban improvements and the organization of public spaces, parks, and monumental buildings that aimed to create a harmonious urban environment. This effort was championed by architects and planners who believed that beautiful public spaces could uplift the community and counter urban issues such as overcrowding and social disorder.

While Brasilia is known for its modernist design, which was influenced by different architectural theories, it does not embody the City Beautiful principles. Similarly, Madrid and Santiago have their own unique urban designs influenced by various historical and architectural movements rather than the specific aesthetic goals of the City Beautiful.
