As we know, pyramids are important, but we do not know what the purpose of them. The whole purpose of the pyramids was basically so the kings and pharaohs could have a tomb to die in. A tomb was a temple that the Egyptians could worship the spirit of the dead. Early tombs were single story buildings called mastabas. The Old Kingdom architect helped design a building made of six mastabas placed on one on top of the other. The mastabas were made out of four mud bricks. Inside a deep chamber was dug, in which the dead were buried. The tombs were the most beautiful and most important part of the pyramid process, they were very important to Egyptian life.
