The Pyramid of Khafre Khafre’s Pyramid, or the 2 nd Pyramid, is easily recognisable by the layers of its original casing stones that still remain near its summit and this, along with the fact that it actually stands on a higher part of the plateau, gives the impression that it is taller than the Great Pyramid. An optical illusion, as it is only 136m (446 ft) tall, with sides of 214.5m (704ft), a surface area of 11 acres and an angle of 53 degrees. It also has lost some of its original height through the years, once being 143.5m (471ft) tall. The only similarity to his father’s Pyramid is the entrance in the same, north facing side. There are no corridors leading into the heart of this Pyramid, the burial chamber being underground, and a long descending passageway has to be negotiated to reach it. This entrance is 50 feet (15m) above ground level, leading to the narrow passage, which descends at a 25-degree angle into the large burial chamber, which measures 14.2m by 5m by 6.9m (46.5ft by 16.5ft by 22.5ft). To take the weight of the pyramid, the roof of the chamber is set at the same angles as the pyramid face. A large, black sarcophagus is found in this room. A lower corridor is directly under the upper corridor, and once contained a portcullis that could be lowered to prevent entry as well as an unfinished burial chamber, which was cut from the bedrock and, it is thought, unused. Like the upper corridor, this one has a 25-degree slope, it then levels out, climbs slightly, and eventually the 2 of them join together. The united passageway then leads to the burial chamber.
