What does a clerestory typically contain?

A clerestory is an architectural feature commonly found in churches and large buildings, characterized by a row of upper windows that are higher than the surrounding roofline. This design element is intended to allow natural light to penetrate the interior space, creating a spiritually uplifting atmosphere, which is particularly important in places of worship. The placement of these windows above the normal viewing height allows for enhanced illumination without compromising the wall space needed for artwork or structural support.

While areas for clergy or community gatherings play essential roles in a church, they do not describe the specific purpose or function of a clerestory. Similarly, the notion of a set of armchairs for worshippers refers to seating arrangements, which are not related to the architectural characteristics or intended functions of a clerestory. Thus, the defining feature of a clerestory remains its role in incorporating upper windows into the building's design.
