The tomb is the northernmost of the three pyramids of the queens[1] 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.
