Shanghai is the most important industrial city of the People’s Republic of China and one of the largest cities in the world. In addition to the city center, which has around 15 million inhabitants, Shanghai also has a number of surrounding municipalities, some 50 km away, with a further 8 million residents.
The first traces of settlement in the region date back to around 4000 BC. In 960, Shanghai was first mentioned as a village. At the end of the 19th century until the 1920s it developed into a world city. Shanghai is now the most modern and western-most similar city in China. The old core has largely been replaced by new buildings and is only available as a tourist attraction.
