The resting place for 13 of the 16 Ming-dynasty (1368–1644) emperors, this is China’s finest example of imperial funerary architecture. The site was selected because of its auspicious feng shui alignment; a ridge of mountains to the north cradles the tombs on three sides, protecting the dead from the evil spirits carried on the north wind. The tombs are spread over 15 square miles (40 sq km). Three (Chang Ling, Ding Ling, and Zhao Ling) have been restored and are always busy. Unrestored, the rest are open but quiet.
