Beaux-Arts architecture (/boʊz ˈɑːr/ bohz AR, French: [boz‿aʁ] ) was the academic architectural style taught at the École des Beaux-Arts in Paris, particularly from the 1830s to the end of the 19th century. It drew upon the principles of French neoclassicism, but also incorporated Gothic and Renaissance elements, and used modern materials, such as iron and glass. It was an important style in France until the end of the 19th century. It also had a strong influence on architecture in the United States because of the many prominent American architects who studied at the École des Beaux-Arts, including Henry Hobson Richardson, John Galen Howard, Daniel Burnham, and Louis Sullivan.
