Which architectural style is inspired by Greek and Roman architecture, featuring columns and elaborate ornamentation?

The Beaux Arts architectural style is characterized by its grandiosity and elaborate beautification, drawing directly from the classical forms of ancient Greece and Rome. It typically includes features such as large columns, arches, and intricate decorative elements that convey a sense of grandeur and sophistication.

The Beaux Arts movement emerged in France, gaining prominence in the late 19th and early 20th centuries and greatly influenced public buildings, cultural institutions, and urban architecture, particularly in cities like Chicago. Notable examples of Beaux Arts architecture can be found in buildings such as the Chicago Public Library and the Field Museum, both of which exhibit the hallmark features of this style, including extensive ornamentation and the use of classical elements.

In contrast, other architectural styles listed, such as Postmodern, Chicago Bungalow, and Prairie, adopt different aesthetics and principles. Postmodern architecture often integrates eclectic and diverse elements and may use irony; Chicago Bungalows focus on modest, functional design; and Prairie style is notable for its horizontal lines and integration with the landscape, moving away from classical ornamentation. These distinctions highlight why Beaux Arts is the correct answer as it directly aligns with the characteristics outlined in the question.
