For the kings of ancient Egypt, the Sun was much more than just a glowing orb in the daytime sky. It was the god Ra, one of the most important of all the gods. Ra was a creator of life, the king’s father, and a representation of the king as a god himself.

So the kings of the Fifth Kingdom, about 4500 years ago, built temples to honor the Sun. Archaeologists have recently excavated about half of the largest one yet discovered – a massive complex that might have been topped by a spot for watching the Sun and stars.

The temple is named “Joy of Ra” or “Joy of the Heart of Ra.” It’s at Abu Gorab, about 10 miles from Cairo, near the ancient capital, Memphis. It was built by King Nyuserre, who reigned for two or three decades. At the time, the kings identified themselves with Ra – as eternal gods. So the temple was a place to honor both Ra and the king.

Excavations have uncovered two large enclosures. The upper level was discovered 125 years ago, but the lower one was found just recently. The upper level included an altar for making offerings to Ra. And one end featured an obelisk that would have towered high above the courtyard and the surrounding landscape. It had a perfect east-west alignment – the directions of the rising and setting Sun.

The recent work also uncovered a stairway to the roof. The rooftop probably served as an observatory – helping Nyuserre follow his “father” across the sky.
