The Coffer inside the King’s Chamber is made of a solid block of granite.
Curiously, despite the fact that the Pyramid is tough to have been built as a tomb, there are no markings that would indicate that. No markings have been found on the coffer inside the King’s Chamber, and there are no hieroglyphs inside the walls of the chamber. This is strange because usually ancient Egyptian tombs were intricately decorated.The Great Pyramid of Giza is also considered one of the best-aligned monuments of ancient times. According to measurements, the pyramid faces true north with 3/60th of a degree of error.
Furthermore, the Pyramid is located at the center of all landmass on Earth. Talk about precision, right?
