Previously considered the longest tomb in the valley until the discovery of the
Tomb of the Sons of Ramesses II, at 137.19 meters (450.10 feet), it contains well preserved reliefs in all but two of its seventeen chambers and side rooms. The design of the tomb follows a "
joggled axis" style of architecture; the tomb entry's descending line is interrupted by a "wiggle" that changes to a sharper angle of descent when entering the tomb following the first chamber. The entry to the tomb consists of four hallways (A–D), each leading further underground; they have a number of murals depicting traditional religious imagery along with illustrations of Seti I before
Ra. Deeper into the tomb, rooms F, Fa, J, Jb, Jc and Jd have intricately carved support pillars with well preserved decorations. It is also one of the first discovered tombs to have a vaulted burial chamber, A tunnel known as corridor K slopes downward from beneath the location where the sarcophagus stood in the burial chamber. In 1960, the first attempt at excavation resulted in the partial clearance of nearly of the tunnel. Due to the poor quality of the rock through which the tunnel was cut, this excavation was abandoned for safety reasons. From 2007 to 2010, the
Supreme Council of Antiquities undertook a second excavation, installing steel supports and a railway system for removing debris. Two staircases were uncovered, with the tunnel ending abruptly at the bottom of the second. The total length of the tunnel is .
Decoration The entry corridors (Corridors B–D) are heavily decorated with symbols of the Pharaoh, like those of
Ma'at and a list of Set's royal names and epithets. Further into the tomb are numerous depictions of King Seti with numerous Gods. Chamber F depicts images of Seti with
Hathor,
Horus and
Neith, along with intact mural examples of the
Book of Gates.The tomb is covered floor to ceiling by detailed murals and reliefs. The ceiling of the vaulted burial chamber depicts a series of astronomical motifs, with golden stars on a deep blue background. Other decorations are religious in nature, including depictions of the
Litany of Ra, the
Book of The Dead,
the Imydwat, the
Book of The Heavenly Cow and depictions of Seti with various deities. There are also depictions of the King alone, standing in the pillars of the room. Each room is heavily decorated, both wall and ceiling, along with numerous columns and floor skirting. Much of the floor skirting is damaged, due to both the ravages of time and the damage due to excavation. Parts of the tomb ceilings have been painted with gold stars on a deep blue sky, a common motif in temples and tombs in Egypt. Numerous rooms in Seti's tomb use the motif, including rooms such as side chamber Jb with the
Imydwat. There are many richly decorated rooms, with their own general themes. == Archaeology and conservation ==
