What is what

The pyramids were the most monumental structures of humanity for many thousands of years. They served as tombs for the god-like kings of ancient Egypt, the pharaohs. These massive burial sites symbolized the ruler's power, which continued in the afterlife. It was believed that he would ascend to the heavens through the pyramid to join his true father, the sun god Ra. The largest and most famous pyramids were built in just one and a half centuries between 2630 and 2472 BC. This period belongs to an early phase of ancient Egyptian culture known as the Old Kingdom. All the pyramids are located on the west bank of the Nile, as the ancient Egyptians believed that the realm of the dead lay in the west, where the sun sets.
