Tutankhamun was buried in a tomb in the Valley of the Kings. It is believed that his early death necessitated a hasty burial in a smaller tomb most likely built for a lesser noble. The body was preserved in the traditional fashion of mummification. Seventy days after his death, Tutankhamun's body was laid to rest and the tomb was sealed. There are no known records of Tutankhamun after his death, and, as a result, he remained virtually unknown until the 1920s. Even the location of his tomb was lost, as its entrance had been covered by the debris from a later-built tomb building.
