What was the first art deco building?

The first building widely recognized as an example of Art Deco architecture is the 1925 Palais de Chaillot in Paris, designed for the Exposition Internationale des Arts Décoratifs et Industriels Modernes. However, some earlier structures, such as the 1922 Chrysler Building in New York City, also showcase early Art Deco elements. The style is characterized by its bold geometric shapes, vibrant colors, and luxurious materials, emerging in the early 20th century and gaining popularity throughout the 1920s and 1930s.
