The Egyptian pyramids are ancient monumental structures built as tombs for pharaohs and important figures in ancient Egypt. The most famous pyramids, including the Great Pyramid of Giza, were constructed during the Old Kingdom period, around 2580 to 2560 BCE. These pyramids were designed to help the deceased transition to the afterlife and were filled with treasures and goods. Constructed primarily from limestone and granite, the pyramids showcase advanced engineering techniques of the time. The Great Pyramid is the largest and was originally 146.6 meters tall. Today, the pyramids remain a significant symbol of ancient Egyptian civilization and attract millions of tourists each year.
