What is the second-largest of the Ancient Egyptian Pyramids of Giza?

The Pyramid of Khafre or of Chephren is the second-tallest and second-largest of the Ancient Egyptian Pyramids of Giza and the tomb of the Fourth-Dynasty pharaoh Khafre (Chefren), who ruled from c. 2558 to 2532 BC.

The pyramid has a base length of 215.5 m (706 ft) and rises up to a height of 136.4 metres (448 ft). It is made of limestone blocks weighing more than 2 tons each. The slope of the pyramid rises at a 53° 13' angle, steeper than its neighbor, the Pyramid of Khufu, which has an angle of 51°50'24". Khafre's pyramid sits on bedrock 10 m (33 ft) higher than Khufu's pyramid, which makes it appear to be taller.

The pyramid was likely opened and robbed during the First Intermediate Period. During the Nineteenth Dynasty, the overseer of temple construction took casing stones to build a temple in Heliopolis on Ramesses II's orders.

Arab historian Ibn Abd al-Salam recorded that the pyramid was opened in 1372 AD. On the wall of the burial chamber, there is an Arabic graffito that probably dates from the same time.
