Neoclassical architecture is an architectural style produced by the Neoclassical movement that began in the mid-18th century in Italy and France then became one the most prominent and iconic architectural styles in the Western World.^[1]

The development of archaeology was crucial in the emergence of Neoclassical architecture. Excavation sites like those in Pompeii and Herculaneum allowed architects to make in depth interpretations of Classical architecture and synthesize their own unique style.^[2]

In form, Neoclassical architecture emphasizes the wall rather than chiaroscuro and maintains separate identities to each of its parts. The style is manifested both in its details as a reaction against the Rococo style of naturalistic ornament, and in its architectural formulae as an outgrowth of some classicising features of the Late Baroque architectural tradition. Therefore, the style defined by symmetry, simple geometry, and social demands instead of ornament.^[3] The classical architecture of today's architects must come under the heading of New Classicism.
