There are three major pyramids in the pyramids necropolis in Giza. If you do not fear small spaces, take the opportunity to step inside the small cavity of the Great Pyramid (for a negotiable tip or fee) to experience the pyramid’s rather daunting descending staircase as well as the king’s and queen’s respective burial chambers.
The Great Pyramid of Khufu is believed to have been built over a twenty-year period and completed around the year 2560 B.C. For centuries, the Pyramid held the record as the tallest
man-made structure in the world. Besides the many theories and symbolism that it embodies, the Pyramid is one of the most breathtaking monuments of Ancient Egypt; take a trip to gaze at its peak and see for yourself.
Although not as magnificently large as the Great Pyramid of Khufu, the Pyramid of Khafra has a more complex interior and a large number of statues dedicated to Khafra, son of Khufu,
including the Sphinx.
The smallest of the three, the Pyramid of Menkara rarely gets the same attention as its two larger neighbours; as it lacks the size of Khufu and the Sphinx of Khafra. Menkara’s one advantage may be its material: the two predecessors used limestone, whereas Menkara used the more valuable and pricier granite in his burial chambers.
