Everyone knows that there are only seven wonders of the world. Not six, not eight, but seven. And despite the fact that almost all of them have disappeared from the face of the earth, this figure has not changed since ancient times. But who actually decides which structure is considered a miracle and which is not? Igor Mozheiko, a science fiction writer, historian and orientalist known as Kir Bulychev, will restore justice. He will tell you where the magical number seven came from, how and by whom the very first wonders of the world were built, and what happened to them later. And it will also supplement their list with many other amazing structures of antiquity, which can rightfully be considered a miracle. In the first book, the reader will learn about the first seven wonders of the world and about the ancient buildings of the Middle East and Central Asia.
