Anotations

Scope note:

Elaborate narthexlike spaces at the west end of some churches, especially in England and France; in some English churches, often porchlike and used as chapels or vestibules. Use normally restricted to a few examples, notably Durham, Ely, and Lincoln cathedrals, Cluny III, and St. Philibert at Tournous. Generally prefer "narthexes" for the entrance porches of early basilican churches and the interior vestibules across the west end of later churches.
