An undecorated tomb in the Valley of the Kings sometimes attributed to Thutmose I of Dynasty 18, in which case it was his original tomb built by Ineni, but it is more likely that of his daughter, Hatshepsut. If the latter, Hatshepsut likely intended it as a double burial with her father, as funerary equipment of both were found there. The tomb descent is very steep, and at 100 yards, is the longest in the Valley of the Kings. Hatshepsut’s sarcophagus is now housed in the Cairo Egyptian Museum, while that of her father is preserved in the Boston Museum of Fine Arts. The tomb was opened in 1799 and recorded by Giovanni Battista Belzoni in 1817 but not entirely cleared until 1903–1904 by Howard Carter. It was reexamined again in 1980.
