5. Cheops Pyramid
The great Pramit, which holds the title of being the tallest building made by human hands for 3,800 years, is 146.5 meters long. The construction of the Great Pramit, which was built as a tomb for the Egyptian Pharaoh Khufu, took 20 years. Considering the architectural conditions of the period, most secrets about the inner labyrinths of the building, which was defined as extraordinary, are still not fully resolved today.
