A hall is the first large apartment beyond the vestibule, and, in the United States, is often long and narrow, serving as a passage to the several apartments. In England, the hall is generally square or oblong, and a long, narrow space of entrance is called a passage, not a hall, as in America. Vestibule is often used in a figurative sense to denote a place of entrance. "The citizens of Rome placed the images of their ancestors in the vestibules of their houses." Bolingbroke
