Egypt has opened two of its oldest pyramids. The pyramids are in Dahshur, south of Egypt's capital city Cairo. They are open to the public for the first time since 1965. Hundreds of people waited outside the Bent Pyramid at an opening ceremony. The Bent Pyramid was built 4,600 years ago for the Egyptian pharaoh Sneferu. It is 101 meters high. Builders used new techniques to build it. The pyramid was an important step in how people built pyramids. There is an 18-metre high "side pyramid" next to the Bent Pyramid. This was built for King Sneferu's wife Hetepheres.
The two pyramids are part of a UNESCO World Heritage Site. Egypt hopes they will boost its tourism industry. Egypt was a top tourist destination but a 2011 uprising changed this. Many people have Egypt's ancient sites on their bucket lists. At the Bent Pyramid, tourists can go through a 79-meter tunnel to two chambers deep inside. They will also be able to see ancient treasures found inside the pyramid. Egyptian archaeologists also found some stone, clay and wooden sarcophagi - the coffins people were buried in. Some of these sarcophagi had mummies inside them.
