This architectural ornamentation dates back to ancient times and has relied on synonyms to describe its characteristic features throughout history. Some of the popular synonyms for clearstory include light well, skyway, and upper window. The term "upper window" is used to confine the concept to a framing design that usually appears above ground level.
