Perpendicular (or panel or rectilinear) tracery


Characterised by large windows with a grid pattern of mullions (uprights) and transoms (horizontals).  Typically, the mullions now pass uninterrupted to the head of the arch.  Developed from the 1320s but continued in use to the early 16th century, and copied later in the Gothic revival.  Also known as panel tracery or rectilinear tracery.
