Pyramid building developed slowly in ancient Egypt. The first pyramids were simple structures called mastabas, which were platforms built over the tombs of importants people. Over the years further levels were added, until a structure called a step pyramid was produced.
In later pyramids, the steps were filled in to produce the smooth conical shape of the famous Pyramids at Giza that we can see today. Pyramid building became an important part of the Egyptian civilization. Egyptians believed that pyramids offered a pathway to heaven for their rulers, the pharoahs, who were buried with items they might need for the afterlife.
