Moderne architecture, also sometimes referred to as Style Moderne or simply Moderne, Jazz Age, Moderne,^[1] jazz modern^[2] or jazz style,^[3][4] describes certain styles of architecture popular from 1925 through the 1940s. It is closely related to Art Deco.^[1]

Originating in the International Exhibition of Modern Decorative and Industrial Arts held in Paris in 1925,^[1] the style has expression in styles traditionally classified as Art Deco, Streamline Moderne, Late Moderne, and, in the U.S., PWA/WPA Moderne. Architectural historian Richard Guy Wilson characterized the style by the eclectic co-existence of "traditionalism and modernism".^[5]

United States

The Moderne style of architecture appears as a descriptor in documentation of many buildings listed by the United States of America's National Register of Historic Places.^[6]

Streamline Moderne

Some Moderne architecture may be classified as Streamline Moderne, an evolution of Art Deco architecture which peaked in popularity c. 1937. This can refer to land-based architecture, such as the Normandie Hotel in San Juan, Puerto Rico, which show curved, shiplike forms and styling. This follows the water-based adaptation of Art Deco decorative style and architecture to passenger ships, such as the SS Normandie. Other Streamline Moderne architecture does not reflect any maritime-oriented themes.^{[citation needed]}
