A style of architecture that emerged in the 1960s and that rejected the traditional principles of classical or modernist architecture, such as symmetry, proportion, and functionality. Postmodern architects often used eclectic or playful elements, such as bright colors, historical references, and asymmetrical shapes, to create buildings that were aesthetically provocative and contextually responsive. Some of the key figures associated with postmodern architecture are Robert Venturi, Frank Gehry, and Zaha Hadid.
