The second largest pyramid in Giza and in all of Egypt was built in honor of Khafre, the third pharaoh of the fourth dynasty during the Old Kingdom period, around 2540 BC. Khafre, also known by the Greek name of Chefren, was the son of Cheops and grandson of Sneferu, another fundamental name in Ancient Egyptian architecture. Khafre lived during the Golden Age of the Old Kingdom. The pyramids built by him and his family were the most majestic in the history of Egypt, and one of the greatest achievements in the history of mankind.
