Greco Deco is a term coined by Washington, DC based art historian James M. Goode to describe a style of art and architecture popularized in the late 1920s and 1930s. Arising out of the Beaux-Arts tradition, Greco Deco combined Greek and Roman traditions with those of the then fashionable Art Deco.
Greco Deco architecture frequently expressed itself in a rather severe Greco-Roman facade decorated with deco styles sculptured panels and/or deco styled interior decoration featuring murals, tile mosaics and sculpture. The style was the almost-official style of many federal and local government buildings in the United States from the mid 1920s until World War II, and frequently overlaps with the style that architectural historian David Gebhard terms "WPA Moderne."
