Question

what is a clerestory?

Explanation:

It is a classic architectural feature, historically used in large structures like ancient Roman basilicas, medieval cathedrals, and modern commercial buildings to enhance interior illumination without relying solely on lower-level windows. The term derives from the Latin clerestaurum meaning "clear story," referring to the lit upper level of a space.

Answer:

A clerestory is an upper section of a wall that contains windows or openings, designed to admit natural light and air into the interior of a building, typically positioned above the main roofline or upper level of adjacent structures.
