Did you know that the Great Pyramid of Giza, one of the Seven Wonders of the Ancient World, was built over 4,500 years ago? The construction of the pyramids required advanced knowledge of geometry, engineering, and mathematics. The pyramids were built using limestone blocks, some of which weighed up to 80 tons. The precise alignment of the pyramids with the cardinal points of the compass is a testament to the ancient Egyptians' astronomical knowledge. Archaeologists believe that the pyramids were built as tombs for pharaohs and were meant to protect their bodies and possessions for eternity. The construction process likely involved thousands of skilled laborers, engineers, and architects working together to create these monumental structures. Despite the passage of millennia, the pyramids still stand as a testament to the ingenuity and skill of the ancient Egyptians. They continue to capture the imagination of people around the world and serve as a reminder of the rich history of architecture and civil engineering.
