Chapel

The word has a variety of uses, not all of them religious. It is widely used in Britain to describe Nonconformist* places of worship, while in Ireland it is often used to refer to Roman Catholic churches. In Europe, since the Middle Ages, a chapel has described the place of worship (which is not a parish church) belonging to a school, college, hospital, palace, etc.; that part of a cathedral or parish church where there is a separate altar/Communion table (often a “Lady Chapel”); and the chancel (hence also sometimes the choir) of a church or cathedral. Specialized usage of the word includes “Chapel Royal” (a church under the direct control of the sovereign), “Chapel of Ease” (a building subordinate to a parish church erected for the ease of parishioners), and “Proprietary Chapel” (primarily an eighteenth or nineteenth century phenomenon, built by subscription and maintained by private individuals but without parochial rights).
