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 each constructing a massive tomb 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 in Dra' Abu el-Naga' (although his mummy was in the Deir el-Bahari tomb cache), Smenkhkare's burial has never been located, and Ramesses VIII seems to have been buried elsewhere.
