Egypt opened two of its oldest pyramids. The pyramids are south of the capital city Cairo. They opened for the first time since 1965. Hundreds of people waited outside at the opening ceremony. The Bent Pyramid is 4,600 years old. It was built for King Sneferu. It is 101 meters high. It changed how people built pyramids. There is an 18-metre high pyramid next to the Bent Pyramid. This was built for King Sneferu's wife Hetepheres.
The pyramids are part of a World Heritage Site. Egypt hopes they will help tourism. Many people want to go to Egypt's ancient sites. At the Bent Pyramid, tourists can go through a 79-meter tunnel deep inside the pyramid. They can see ancient treasures found inside the pyramid. Egyptian archaeologists found some stone, clay and wooden sarcophagi. These are coffins for burying people in. Some of the sarcophagi had mummies inside them.
