The world-famous "Abu Simbel Temple" in ancient Egypt.

Pharaoh Ramses II , who reigned for 68 years and lived to the age of 91. Walking into the scenic area, you will be greeted by a very shocking mountain-carved archway gate with four 20-meter-high statues of Ramses II on the front, surrounded by several small statues of wives and children at his knees and sides. These four huge statues also serve as pillars, supporting a 30-meter-high temple. Walking into the cave palace, there is a rectangular hall with a main body of 60 meters long, with 16 statues arranged in two rows on the left and right, all of which are also Ramses II himself. At the end of the hall is a stone chamber used as an altar, with four statues sitting side by side, from left to right, the god of darkness, the god of the sky, Ramses II himself, and the sun god. The magic of the altar is that only on Ramses II's birthday on February 22nd and the foundation day on October 22nd each year, sunlight will shine through the gate and illuminate three of the four statues in the innermost stone chamber, while the god of darkness will always be hidden in the darkness that sunlight cannot reach. From this point, it shows the amazing achievements of the ancient Egyptians in astronomy, calendar, and mathematics.
