The pyramid of Teti, who was the first king of the Sixth Dynasty, has suffered enormous damage from quarrymen, who removed the covering and limestone slabs within the monument. The pyramid was originally 52.5m high, and each side was 78.5m in length.
The pyramid of Unas, who was the last pharaoh of the Fifth Dynasty, is nowadays rather dilapidated. All of its outer covering has vanished except for that on the southern face, where a few of the limestone blocks were restored in ancient times. The original height of the pyramid was 43m and the length of each side is 57.5m.
King Userkaf of the Fifth Dynasty wanted to have his pyramid as near to the Step Pyramid as possible, so as to be close to one of his great predecessors, King Djoser. Thus, Userkaf built his pyramid about 200 meters or 656 feet from the northeast corner of the Step Pyramid. The Pyramid of Userkaf is not in a good condition. Nothing of importance was found.
The Pyramid of Menkaure is the smallest one on the Giza plateau and is 66 meters or 216 feet high. It is built on the edge of the sloping plateau. This pyramid was finished by King Shepseskaf, the successor to King Menkaure.
