The tomb has some of the most diverse decoration in the Valley of the Kings. In fact Ramesses VI, in a break with tradition, used the decoration program of the Osireion at Abydos as the template for his tomb. Its layout consists of a long corridor, divided by
pilasters into several sections, leading to a pillared hall, from which a second long corridor descends to the burial chamber. The digging of the burial chamber was not fully completed; its back wall has two pillars which are still connected to the wall behind them instead of standing separate. The ceilings are decorated with astronomical figures and constellations in the first few divisions of the corridor, while in the last two divisions, and continuing into the first hall [designated Hall E by Piankoff], is a double presentation of both the Book of the Day and the Book of the Night, framed by an elongated image of the goddess
Nut. The ramp descending to the next corridor is flanked on either side by two images of winged cobras with crowns, representing the goddesses of Upper and Lower Egypt.

Second corridor The decorations show scenes of 11 hours from the Book of the Amduat in sequential order, although hours 7-11 are abbreviated . The ceiling depicts the barques of Ra and the Books of the Day and Night.
Antechamber and Burial Chamber Ramesses VI is shown before
Hekau, and
Maat in the antechamber [Hall H, the Hall of Two Truths] at the end of the corridor, preceding the burial chamber. It contains important transfiguration spells (Chapters 124-127 and 129) from the
Book of the Dead. The walls of the cavernous burial chamber are decorated with the
Books of the Earth (including the Book of
Aker). These include images of a solar boat with the double-headed god Aker, images of Osiris and various gods, the destruction of enemies, and representations of the sun's rays resurrecting various figures. A detailed analysis of these complex scenes are in J. Roberson, The Ancient Egyptian Books of the Earth. The vaulted ceiling of the chamber is decorated, once again, with the Book of the Day and the Book of the Night, framed by a double elongated image of Nut.
