One of the things that makes Egypt unique is the Great Pyramid of Giza. It is the most accurate structure in existence facing true north with only 3/60th degree error.
This has baffled many historians because the pyramid was made using over 100,000 slaves with no machines other than what was available in 2560 B.c.
The Pyramid of Khufu is the largest Egyptian Pyramid ever built. The Khufu Pyramid was built by Pharaoh Khufu in 2560 BC and it’s 147 metres tall.
