Menkaure's Pyramid had an original height of 66.5 metres (218 feet). It now stands at 61 m (204 ft) tall with a base of 108.5 m . Its angle of incline is approximately 51°20′25″. It was constructed of limestone and granite. The first sixteen courses of the exterior were made of granite. The upper portion was cased in the normal manner with Tura limestone. Part of the granite was left in the rough. Incomplete projects like this help archeologists understand the methods used to build pyramids and temples. South of the pyramid of Menkaure were 3 satellite pyramids none of which appear to have been completed. The largest was made partly in granite like the main pyramid. Neither of the other 2 progressed beyond the construction of the inner core.
