(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 had an early use in certain Egyptian temples, as at Karnak, and was used later in the great halls of Roman basilicas. It became a characteristic element of medieval churches, receiving its fullest development in churches of the Gothic period.


An upper story or row of windows rising above the adjoining parts of the building, designed as a means of admitting increased light into the inner space of the building.


The upward extension of enclosed space achieved by bringing a windowed wall up to interrupt the slope of the roof.
