Pyramid G1 a

G1-a is one of the subsidiary pyramids of the Giza East Field of the Giza Necropolis, located immediately to the eastern side of the Great Pyramid of Giza. It was built during the Fourth dynasty of Egypt. The tomb is the northernmost of the three pyramids of the queens and has a base of 49.5 metres (162 ft) wide and originally a height of 30.25 metres (99.2 ft); the pyramid has lost two-thirds of its original height. In the west wall of the burial chamber a small niche was dug in which were found fragments of basalt. It is also known as the Pyramid of Hetepheres I as discovered by Mark Lehner; it was originally thought to belong to Queen Meritites I.
