After the First World War, art deco buildings of steel and reinforced concrete began to appear in large cities across Europe and the United States. In the United States the style was most commonly used for office buildings, government buildings, movie theaters, and railroad stations. It sometimes was combined with other styles; Los Angeles City Hall combined Art Deco with a roof based on the ancient Greek Mausoleum at Halicarnassus, while the Los Angeles railroad station combined Deco with Spanish mission architecture. Art Deco elements also appeared in engineering projects, including the towers of the Golden Gate Bridge and the intake towers of Hoover Dam. In the 1920s and 1930s it became a truly international style, with examples including the Palacio de Bellas Artes (Palace of Fine Arts) in Mexico City by , the Mayakovskaya Metro Station in Moscow and the National Diet Building in Tokyo by Watanabe Fukuzo.
