Tomb KV47, located in the Valley of the Kings in Egypt, was used for the burial of Pharaoh Siptah of the Nineteenth Dynasty. It was discovered on December 18, 1905 by Edward R. Ayrton, excavating on behalf of Theodore M. Davis; Siptah's mummy had been found earlier, cached in KV35. It was the last of the Nineteenth and Twentieth Dynasty kings tombs to be uncovered in the Valley. Ayrton stopped his excavation in 1907 due to safety fears, and Harry Burton returned in 1912 to dig further. The cutting of a side passage was halted after the workmen cut into Side Chamber Ja of the tomb of Tia'a (KV32). The tomb was unfinished at the time of its use.
