Situated south of the main pyramid between satellites G3-a and G3-c, this structure contained the body of a woman.

[1] The pyramid was built during the Fourth Dynasty of Egypt, presumably for one of the wives of Menkaure.

The American archaeologist George Andrew Reisner has speculated that the queen buried in the pyramid may have been Menkaure's half-sister, Shepsetkau, the daughter of Meresankh III and Khafre.

[2] The surface of the pyramid is stepped, consisting of four platforms that decrease toward the top.

The pyramid's base is 31.24 metres (102.5 ft) square.
