 The style is known as Geometric Decorated Gothic and can be seen to splendid effect at many English cathedrals and major churches, where both the eastern and the western terminations of the building may be occupied by a single large window such as the east window at Lincoln and the west window at Worcester Cathedral.Windows of complex design and of three or more "lights" or vertical sections, are often designed by overlapping two or more equilateral arches springing from the vertical mullions.Rayonnant is the term used particularly to described the style that produced the great rose windows of France.
