The Great Wall is a great achievement not only in Chinese but in world architecture too. And the old Chinese saying, "He who hasn"t been to the Great Wall is not a true man", show the profound impact it has had on the mind of many. This book surveys the history and construction of the Great Wall, including a discussion of the three eras of building - the Qin, the Han and Ming dynasties. Also presented is a detailed explanation of the functions of its various facilities, and the communications, defence, and drainage systems. In addition, descriptions of cultural artefacts (which include the tomb murals of the Han dynasty in Horinger, the Buddhist scriptures in six languages in Yuntai, the ancient travel permits and inscribed wooden slips) and related legendary tales will certainly arouse the interest of not only the general reader but the intrepid traveller as well!
