Neoclassical architecture is characterized by grandeur of scale, simplicity of geometric forms, dramatic use of columns and a preference for blank walls. Much of this style is inspired by the classical architecture of ancient Greece and Rome. If you look closely at a Neoclassical building you may see echoes of the Parthenon in Athens or the Pantheon in Rome. Yet, Neoclassicism is not actually any one distinct style but a trend, or approach to design, that can incorporate a variety of styles. Neoclassical buildings have many (although not necessarily all) of these features: symmetrical shape, tall columns that rise the full height of the building, triangular pediment and a domed roof.
