Answer: Rameses II was one of the greatest pharaohs Egypt ever had. He ruled for almost 67 years, perhaps no pharaoh has ruled so much. It was a great builder and a great fighter. It became famous because of the great battle of Kadesh.
During the construction of the two temples in Abu Simbel, the Great Temple named after Rameses, and the Little Temple for his wife Nefertari, hundreds of workers had to carve the entire temple on the rock of a sandstone hill, an admirable detail because any serious error would cause the entire work to sink.
Designers were hung by scaffolding to draw on the rock. Then came the excavators and carved four colossal statues of Ramesses II. The inner sanctuary, carved out of a solid rock, extending 55 meters deep, was the most sacred place in the Great Temple.
In it four statues, that of Pharaoh and those of three gods, are seated. Twice a year, thanks to the architects' calculations, at midsummer, harvest time, as the sun rises, its rays shine through the walls decorated with the bloody feats of the battle of Kadesh and illuminate the divine statues. The construction took 20 years.
Pharaoh also built other temples far from any Egyptian city, but which crossed the path of foreigners. His intention was to show the grandeur of Egypt. The temples are near the bank of the Nile, meaning whoever climbs the Nile will see the statues of the king of Egypt on his throne. Ramses only created these temples and other works as a pharaonic "propaganda" of his power.
