Usage: {Vestibule}, {Hall}, {Passage}. A vestibule is a small
       apartment within the doors of a building. 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.''
