Neoclassical architecture, sometimes referred to as Classical Revival architecture, is an architectural style produced by the Neoclassical movement that began in the mid-18th century in Italy, France and Germany. It became one of the most prominent architectural styles in the Western world. The prevailing styles of architecture in most of Europe for the previous two centuries, Renaissance architecture and Baroque architecture, already represented partial revivals of the Classical architecture of ancient Rome and ancient Greek architecture, but the Neoclassical movement aimed to strip away the excesses of Late Baroque and return to a purer, more complete, and more authentic classical style, adapted to modern purposes.

Greek Revival architecture was a style that began in the middle of the 18th century but which particularly flourished in the late 18th and early 19th centuries, predominantly in northern Europe, the United States, and Canada, as well as in Greece itself following its independence in 1821. It revived many aspects of the forms and styles of ancient Greek architecture, in particular the Greek temple. A product of Hellenism, Greek Revival architecture is looked upon as the last phase in the development of Neoclassical architecture, which was drawn from Roman architecture. The term was first used by Charles Robert Cockerell in a lecture he gave as an architecture professor at the Royal Academy of Arts in London in 1842.
