1923, worked for a short time with Frank Lloyd Wright, also quickly became a force in American architecture through his modernist design for the same client, the Lovell Health House in Los Angeles. Neutra's most notable architectural work was the Kaufmann Desert House in 1946, and he designed hundreds of further projects. Paris International Exposition of 1937 and the architecture of dictators The 1937 Paris International Exposition in Paris effectively marked the end of the Art Deco, and of pre-war architectural styles. Most of the pavilions were in a neoclassical Deco style, with colonnades and sculptural decoration. The pavilions of Nazi Germany, designed by Albert Speer, in a German neoclassical style topped by eagle and swastika, faced the pavilion of the Soviet Union, topped by enormous statues of a worker and a peasant carrying a hammer and sickle. As to the modernists, Le Corbusier was practically, but not quite invisible at the Exposition; he participated in the Pavilion des temps nouveaux, but focused mainly on his painting. The one modernist who did attract attention was a collaborator of Le Corbusier, Josep Lluis Sert, the Spanish architect, whose pavilion of the Second Spanish Republic was pure modernist glass and steel box. Inside it displayed the most modernist work of the Exposition, the painting Guernica by Pablo Picasso. The original building was destroyed after the Exposition, but it was recreated in 1992 in Barcelona. The rise of nationalism in the 1930s was reflected in the Fascist architecture of Italy, and Nazi architecture of Germany, based on classical styles and designed to express power and grandeur. The Nazi architecture, much of it designed by Albert Speer, was intended to awe the spectators by its huge scale. Adolf Hitler intended to turn Berlin into the capital of Europe, grander than Rome or Paris. The Nazis closed the Bauhaus, and the most prominent modern architects soon departed for Britain or the United States. In Italy, Benito Mussolini wished to present himself as the heir to the glory and empire of ancient Rome. Mussolini's government was not as hostile to modernism as The Nazis; the spirit of Italian Rationalism of the 1920s continued, with the work of architect Giuseppe Terragni. His Casa del Fascio in Como, headquarters of the local Fascist party, was a perfectly modernist building, with geometric proportions (33.2 meters long by 16.6 meters high), a clean façade of marble, and a Renaissance-inspired interior
