The ancient structure built as a tomb for Pharaoh Khufu is the Great Pyramid of Giza, one of the most iconic monuments of ancient Egypt. Constructed around 2580–2560 BCE during the Fourth Dynasty of the Old Kingdom, it was originally 146.6 meters tall and is the largest of the three pyramids at Giza. The Great Pyramid showcases the architectural prowess of the ancient Egyptians, employing advanced engineering techniques and a workforce comprised of skilled laborers, not slaves as often believed. It served not only as Khufu’s final resting place but also stood as a testament to the society's beliefs in the afterlife and the power of the pharaohs.
