Passage: Henutsen was most possibly interred in pyramid G1-c. Egyptologists believe that this pyramid was originally not part of Khufu's pyramid complex, but later added, as its southern side is not aligned with that of the Great Pyramid. In fact, the pyramid's southern side is aligned with Khufukhaf's mastaba tomb nearby. Rainer Stadelmann additionally believes that prince Khufukhaf was identical to king Khafra and that Khafra erected G1-c as the tomb for his (now royal) mother. Pyramid G1-c was long time thought to be a satellite pyramid, because it did not come with a boat pit, as it was the case for the pyramids G1-a and G1-b. G1-c was later identified as an unfinished pyramid which was constructed in a hurry.
