The Great Pyramid of Giza, which is also called the Pyramid of Khufu. Reports vary by how much larger the pyramids are; some say it’s even twice as wide as it is tall.
The great pyramid of Giza (also known as Pyramid of Khufu) has a total volume 210,000 cubic meters (814,633 cubic feet). That makes its dimensions about 43 by 60 meters at base and 147 metres high; 1 pyramid inch equals 2.54 centimeters.
The great pyramid in Giza is located just outside Cairo in modern day Egypt. It was constructed with the ambition to serve as a continued tomb for emperor Khufu, who was said to have ruled until 2584 BC.
How it Conducts Solar Observations:
If you were curious about how exactly this ancient structure conducted solar observations (watching the sun’s trajectory), you would be quite impressed by its highly developed engineering skills and technology! Essentially, one could calculate when an equinox occurred based on when it passes through the southern shaft of King’s chamber inside of the Great Pyramid of Giza. This complex design is also constructed with perfect symmetry that reflects temporal (daily) and celestial.
