G1-b 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 central of the three pyramids of the queens, located ten meters south of the Pyramid G1-a. It has a square base 49 feet square and had an original height of 30 metres. Egyptologists Mark Lehner and Rainer Stadelmann attribute it to the queen Meritites I. Zahi Hawass, however, attributes it to Queen Noubet who gave birth to Djedefre.
