Building of the tomb was started in year 2 of Seti II rule. It became burial place of Taweseret, also mummy of pharaoh Seti II was moved there from KV15 tomb. After the tomb had been adopted by Setnakht, mummy of Seti II returned to its previous tomb. Mummy of the queen Taweseret got to the KV35 tomb-cache at the time of the general replacement of royal mummies. The tomb has lain open since antiquity. In completing the tomb Setnakht excavated one of the largest tombs (over 112 m) in the valley. The sarcophagus of Setnakht was smashed in antiquity. The lid is closely similiar to that of Siptah, with the figure of the king flanked to left and right by images of Isis and Nephtys. Mummy of king was found among the royal mummies in tomb-cache KV35.
