Stripped Classicism is a late subset of classically influenced architecture popular from 1910 to 1940. Though it employs the massing and materiality of Neoclassical/Beaux-Arts designs, it features either abstracted ornamentation or none at all. It had a tendency to be used by fascist and totalitarian regimes such as Nazi Germany and fascist Italy, but it was equally used by the Works Progress Administration in the United States.
The earliest examples of Stripped Classical architecture date to the 1910s. A design that established the style was the German Embassy in St. Petersburg designed by Peter Behrens, which employs simple unfluted Doric columns and pilasters, an undecorated cornice, and the common stone materiality of Neoclassical architecture. It remained popular through the following two decades as Modernism and its related styles shifted priorities from historicist architecture to one that was supposedly new and pure.
Stripped Classicism is characterized by its "starving" of classical architecture's features. Though features such as organization, massing, and materiality remain intact, the orders and ornamentation that characterized classical architecture have been stripped away. Columns may be unfluted with a very simple Doric-esque capital, or fluted with no capital at all. Round columns are not always the norm--others can be square, or replaced by pilasters instead. Cornices are either very simple or absent entirely. Stripped Classical buildings are dense and strong in massing, often being at a large scale. Its program is almost exclusively governmental or institutional buildings.
Stripped Classicism mostly fell out of favor in the United States by the 1940s, as it was replaced by the nation's embrace of Modernism after World War II.
