万里长城是全世界最著名的建筑物，但是由于它绝大部分地处偏僻，人们对它的了解与它的盛名并不相称。本书是长城保护领域里程碑式的作品，它首次以重摄老照片的方式来讲述长城百年变迁的沧桑故事。作者使用重摄技术，真实、直观地再现了它的过去和现在。

《万里长城，百年回望-从玉门关到老龙头》的图书和展览只是忠实地记录长城的今昔。正因为忠于事实，忠于历史，本书将启发读者思考怎样做才能最有效地保护长城，才能让既是中华民族的象征又是世界文化遗产的万里长城万世永存。

Using the technique of rephotography-repeat photography at the same place with a time lag in between-this landmark volume，the first mainstream publication on the theme of Great Wall conservation，presents a realistic portrait of the world's most-famous building。

William Lindesay spent three years travelling 35,000 km across North China，carrying his tripod，cameras and a file of vintage photographs，the earliest dating from 1871，looking not merely for vantage points，but‘advantage points’，places from which he could see the Great Wall in the past and present，side by side。

The Great Wall Revisited presents 72 of the most elucidating‘then’and‘now’comparisons，succinct histories of the sites，and colourful literary impressions left by‘miIestoRe’Visitors，juxtaposed beside contemporary eyewitnesses accounts that explain the changes。This dossier unfolds as an extraordinary journey along the Wall from the Jade Gate in northwest China's gobi to Old Dragon's Head on the Yellow Sea coast。

A state of the Great Wall report per se，evidencing the vestiges of time which have impacted upon it，this book will trigger a lively forum，while asking poignant questions as to how the Wall should best be preserved for present and future generations。
