Clerestory

A clerestory ( KLEER-stor-ee; lit. 'clear storey', also clearstory, clearstorey, or overstorey; from Old French: cler estor) is a high section of wall that contains windows above eye level. Its purpose is to admit light, fresh air, or both. Historically, a clerestory formed an upper level of a Roman basilica or of the nave of a Romanesque or Gothic church, the walls of which rise above the rooflines of the lower aisles and are pierced with windows. In addition to architecture, clerestories have been used in transportation vehicles such as buses and trains to provide additional lighting, ventilation, or headroom.
