Palladian window

Palladian architecture is a European style of architecture derived from and inspired by the designs of the Venetian architect Andrea Palladio (1508–1580). That which is recognised as Palladian architecture today is an evolution of Palladio's original concepts. Palladio's work was strongly based on the symmetry, perspective and values of the formal classical temple architecture of the Ancient Greeks and Romans. From the 17th century Palladio's interpretation of this classical architecture was adapted as the style known as Palladianism. It continued to develop until the end of the 18th century.

Palladianism became popular briefly in Britain during the mid-17th century, but its flowering was cut short by the onset of the Civil War and the imposition of austerity which followed. In the early 18th century it returned to fashion, not only in England but also, directly influenced from Britain, in Prussia. Count Francesco Algarotti may have written to Burlington from Berlin that he was recommending to Frederick the Great the adoption in Prussia of the architectural style Burlington had introduced in England but Knobelsdorff's opera house on the Unter den Linden, based on Campbell's Wanstead House, had been constructed from 1741. Later in the century, when the style was falling from favour in Europe, it had a surge in popularity throughout the British colonies in North America, highlighted by examples such as Drayton Hall in South Carolina, the Redwood Library in Newport, Rhode Island, the Morris-Jumel Mansion in New York City, the Hammond-Harwood House in Annapolis, Maryland, and Thomas Jefferson's Monticello and Poplar Forest in Virginia.
