An intermediate room or hallway connecting two larger spaces; a transitional architectural space.
French from entre (between) + salle (room); describes an in-between chamber or gallery.
Palace designers used entresalles deliberately—those awkward connector rooms weren't wasted space but psychological transitions that prepared guests for the grandeur of the next room, like a pause before the big reveal.
