Oeil de boeuf: in English, “eye of the steer”, “bull’s eye”, “ox eye” – these are all common translations.
This architectural detail is defined as a small, round or oval window. Furthermore, it is usually placed in an attic space.
Today, this style of window is seen all over the world, but it originated in 17th century France and England. For the French, the oeil de boeuf was an outstanding example of Baroque Style.
