Valley of the Kings WV25 may have originally been intended for him. With the return to religious orthodoxy at the end of the Eighteenth Dynasty, Tutankhamun, Ay, and Horemheb returned to the royal necropolis. The Nineteenth and Twentieth Dynasties saw an increase in the number of burials (both here and in the Valley of the Queens), with Ramesses II and later Ramesses III constructing a massive tomb that was used for the burial of their sons (KV5 and KV3 respectively). There are some kings that are not buried within the valley or whose tomb has not been located: Thutmose II may have been buried
Minor tombs in the Valley of the Kings are larger, multiple chambered tombs. These minor tombs served various purposes, some were intended for burials of lesser royalty or for private burials, some contained animal burials and others apparently never received a primary burial. In many cases these tombs also served secondary functions and later intrusive material has been found related to these secondary activities. While some of these tombs have been open since antiquity, the majority were discovered in the 19th and early 20th centuries during the height of exploration in the valley. Tombs in the Valley of the Kings are assigned a numerical "KV" (for Kings' Valley)
