And, it is the oldest and biggest of the three pyramids which make up the Giza pyramid complex. This colossal structure held the record as the world’s tallest human-made structure for over 3,800 years. This changed in 2010, when the UAE built the Burj Khalifa. The Great Pyramid’s precise construction uses an estimated 2.3 million limestone blocks and continues to baffle modern engineers and archaeologists. What they can all agree on, though, is that it is incredible.
