A Palladian arch window, also known as a Venetian window, is a distinctive architectural element, rich in history, visual impact, and functionality. Typically, it consists of a central, taller, wider round-arched window flanked by two narrower, shorter sections having flat or square tops.
A venetian window is hailed as a triumphal arch of fenestration, which envelopes wall apertures with a sense of pomp and grandeur.
Having first appeared in Renaissance Italy, the Palladian arched windows have been used for over 500 years in Italy, Europe, the US, and other parts of the world. This tripartite architectural style has also been applied to doors of palaces and monumental buildings for centuries.
The three elements of the Palladian windows are symmetrical and proportionate in arrangement and sizes. If the central arched section is 7 ft high and 5 ft wide, each of the flanking rectangular windows would typically measure 5.5 to 6 ft high and 3.5 to 4 ft wide, making the central opening both significantly taller and wider. The side window openings are topped lintels and supported by columns.
