The Pyramids.
The Pyramids in Cairo are my favourite buildings in the whole world. I knew all about them when I was very young. They have always fascinated me. They really are one of the world's wonders. People still do not know how they were built. I think they are probably the greatest architectural achievement ever. Even the tallest buildings today are easy to build. The Pyramids were almost impossible to build, but they did it. I love looking at photos of The Pyramids. When I visited Egypt, their beauty blew me away. And the great thing was I also felt their mystery. The Pyramids are full of hidden secrets, history and mysteries.
