The ancient capital of six dynasties on the Yangtze: Ming-era city walls, the Sun Yat-sen Mausoleum on Zijinshan and gardens hidden away among the blocks of the modern city.
Nanjing is the "Southern Capital", and it has been the capital of China several times over: under the six dynasties of the first millennium, under the early Ming and under the Republic of China. Something has survived from each layer, and unlike neighbouring Shanghai, Nanjing reads as a historic city rather than a shop window. It is also green and noticeably calmer than most Chinese cities of a million and more.
Nanjing's chief distinction is its city wall of the late 14th century, built under the first Ming emperor. About 25 km of the original perimeter survives, making it the longest surviving city wall in the world. It follows the terrain, curving around the hills and the lake.
In December 1937 the Japanese army took Nanjing; the mass killings and violence against the civilian population that followed are known as the Nanjing Massacre. Estimates of the number of dead differ and remain a subject of dispute among historians. The event is commemorated by the Memorial Hall for the Victims of the Nanjing Massacre in the western part of the city; entry is free but registration is required.
One day covers the centre and no more: Zhonghua Gate, the Fuzimiao quarter and Zhanyuan Garden. A second day goes entirely on Purple Mountain with the Sun Yat-sen Mausoleum, the Xiaoling tomb and the Linggu Temple, where there is a great deal of walking and it is not worth combining the mountain with anything else. Three days is the ideal, adding the Nanjing Museum, the Presidential Palace and the memorial.
The metro is well developed, but Purple Mountain is large: inside it you either ride electric buggies or walk several kilometres at a stretch.
Nanjing fits neatly into a route along the lower Yangtze. Shanghai is a little over an hour away by high-speed train, Suzhou and Wuxi less than an hour, Hangzhou about an hour and a half. The logical combination is Shanghai, Suzhou, Nanjing: Nanjing supplies the ancient capital, Suzhou the gardens.
October and November: dry, cool, with Purple Mountain in autumn colour. April is good for the blossom but crowded. Nanjing is one of the "furnaces on the Yangtze", so from June to August it is hot and very humid, while the winter is damp and raw.
Nanjing requires an interest in history. Without one the city falls apart into a set of scattered sites in the middle of an ordinary megacity: there is no single old centre, 20th-century building fills almost everything, and the distances are long. Fuzimiao, which many people take for "old Nanjing", is almost entirely a modern reconstruction with shopping arcades. The 1937 memorial is heavy going and should not be squeezed in between a garden and dinner. For landscapes and modernity Shanghai is the better choice, since Nanjing is about the layers of the past.
