What shape is a fanlight window?

A fanlight window is characterized by its distinctive semicircular shape. This type of window is typically situated above a door and features a radius that forms a curved top, resembling a half-circle. Traditionally, fanlights are designed with decorative glass panes, which may include intricate patterns or designs, enhancing the aesthetic appeal of an entrance.

The semicircular design of a fanlight serves both functional and decorative purposes. It allows for additional natural light to enter the space while also providing a visually pleasing architectural element. The use of curved shapes in architecture often adds softness and elegance to building facades.

Understanding the shape and function of fanlight windows can help in identifying them in various architectural styles, particularly in colonial and classical designs.
