(both: klĭr`stōr'ē, –stôr'ē), a part of a building whose walls rise higher than the roofs of adjoining parts of the structure. Pierced by windows, it is chiefly a device for obtaining extra light.

It became a characteristic element of medieval churches, receiving its fullest development in churches of the Gothic period.
