Classical architecture is architecture derived in part from the Greek and Roman architecture of classical antiquity, enriched by classicizing architectural practice in Europe since the Renaissance. Classical architecture has inspired many more recent architects and has led to revivals such as neoclassical architecture from the mid-18th century and the Greek Revival of the 19th century. After a brief period of eclecticism, the classical style reigned again from the late 19th century until the second world war, though it continues to inform many architects to this day.
The term "classical architecture" also applies to any mode of architecture that has evolved to a highly refined state, such as classical Chinese architecture, or classical Mayan architecture. It can also refer to any architecture that employs classical aesthetic philosophy.
