Postmodern architecture began as an international style the first examples of which are generally cited as being from the 1950s, but did not become a movement until the late 1970s and continues to influence present-day architecture. Postmodernity in architecture is said to be heralded by the return of "wit, ornament and reference" to architecture in response to the formalism of the International Style of modernism. As with many cultural movements, some of Postmodernism's most pronounced and visible ideas can be seen in architecture. The functional and formalized shapes and spaces of the modernist style are replaced by diverse aesthetics: styles collide, form is adopted for its own sake, and new ways of viewing familiar styles and space abound. Perhaps most obviously, architects rediscovered past architectural ornament and forms which had been abstracted by the Modernist architects.
