Hi

A Venetian window is a kind of window designed in the style of the Venetian architect Andrea Palladio, who lived and worked in the 16th century. This kind of window consists of three windows, the central one being larger than the other two and topped with an arch. As the design is often attributed to Palladio's work, these kinds of windows are also sometimes called Palladian windows. Yet another name for these kinds of windows is Serlian windows, which comes from the writings of Sebastiano Serlio, who live in the late 15th and early to mid-16th century and wrote about the design in a multi-volume book about architecture.
