"The term false door (also ka-door, false- door stela, fausse-porte, Scheintiir) denotes an architectural element that is found mostly in private tomb structures of the Old Kingdom (mastabas and rock-cut tombs): a recessed niche, either in the western wall of the offering chamber, or in the eastern tomb facade. It imitates the most important parts of an Egyptian door, but the niche offers no real entrance to any interior space. Such fictitious doors are also attested in other architectural contexts" in Redford, Donald B. (2001). The Oxford Encyclopedia of Ancient Egypt: A-F (dalam bahasa Inggris).
