The pyramids were designed to protect the bodies of the pharaohs and their treasures from grave robbers. The ancient Egyptians believed that the pharaohs were divine and that they would continue to live in the afterlife. The pyramids were built with large, heavy stones to make them as strong as possible, preventing the tomb from being broken into, the bodies from being stolen, and the spirits from escaping.
Pyramids were also built to show the power and wealth of the pharaohs. The larger the pyramid, the more powerful and wealthy the pharaoh was believed to be. The pyramids also served as a way to honor the pharaohs and to ensure that they would be remembered for eternity.
The first pyramids were built in the 27th century BC. The largest pyramid, the Great Pyramid of Giza, was built by the pharaoh Khufu and took an estimated 20 years to build. The Great Pyramid is one of the Seven Wonders of the Ancient World and is still standing today.
Pyramids continued to be built in Egypt until the 13th century AD. However, by this time, they were no longer used as tombs for pharaohs. Instead, they were used as temples and monuments.
