G1-c is one of the subsidiary pyramids of the Giza East Field of the Giza Necropolis immediately to the eastern side of the Great Pyramid of Giza, built during the Fourth dynasty of Egypt. It is the southern of the three pyramids of the queens and is the one of Queen Henutsen.
It is 46.25 metres wide and had a height of 29.60 metres. A niche, four inches deep was dug in the south wall of the burial chamber. Pyramid G 1c was originally not a part of Khufu's pyramid complex, as its southern side is aligned not with the side of the Great Pyramid, but with Khufukhaf I's mastaba tomb nearby. Pyramid G 1c was at some point thought to possibly be a satellite pyramid, because it did not come with a boat pit like pyramids G 1a and G 1b.
