It is located in the Datong Basin at an elevation of and borders Inner Mongolia to the north and west and Hebei to the east. It had a population of 3,318,057 during the 2010 census, of whom 1,629,035 lived in the built-up area made of the three urban districts of Chengqu, Kuangqu and Nanjiao.

History

The area of present-day Datong was close to the Beidi state of Dai, which was conquered by the Zhao clan of Jin in 457 BC. It was a frontier land between the agricultural Chinese and Beidi and the nomads of the Eurasian steppe. The area was well known for its trade in horses.
Pingcheng County formed part of the Qin commandery of Yanmen. It continued under the Han, who founded a site within present-day Datong in 200BC following their victory against the Xiongnu nomads at the Battle of Baideng. Located near a pass to Inner Mongolia along the Great Wall, Pingcheng blossomed during the following period and became a stop-off point for camel caravans moving from China into Mongolia and beyond. It was sacked at the end of the Eastern Han. Pingcheng became the capital of Northern Wei from AD398–494. The Yungang Grottoes were constructed during the later part of this period. During the mid to late 520s, Pingcheng was the seat of Northern Wei's Dai Commandery.
The city was renamed Datong in 1048. It was the Xijing of the Jurchen Jin dynasty prior to being sacked by the Mongols. It was sacked again at the end of the Ming in 1649, but promptly rebuilt in 1652.

Geography

Datong is the northernmost city of Shanxi, and is located in the Datong Basin, with an administrative area spanning latitude 39° 03'–40° 44' N and longitude 112° 34'–114° 33' E. The urban area is surrounded on three sides by mountains, with passes only to the east and southwest. Within the prefecture-level city elevations generally increase from southeast to northwest. Datong borders Ulanqab to the northwest and Zhangjiakou to the east, Shuozhou to the southwest and Xinzhou to the south.
The well-known Datong Volcanic Arc lies nearby in the Datong Basin.

Climate

Datong has a continental, monsoon-influenced steppe climate, influenced by the + elevation, with rather long, cold, very dry winters, and very warm summers. Monthly mean temperatures range from in January to in July; the annual mean temperature is. Due to the aridity and elevation, diurnal temperature variation is often large, averaging annually. There barely is any precipitation during winter, and more than of the annual precipitation occurs from June to September. With monthly percent possible sunshine ranging from 54% in July to 66% in October, sunshine is abundant year-round, and the city receives 2,671 hours of bright sunshine per year.

Administrative divisions

The Yungang Grottoes are a collection of shallow caves located west of Datong. There are over 50,000 carved images and statues of Buddhas and bodhisattvas within these grottoes, ranging from 4 centimeters to 7 meters tall. Most of these icons are around 1000 years old.
Within the city itself, there are a few surviving sites of historical interest such as the Nine-Dragon Wall, the Huayan Monastery, and the Shanhua Temple. Further afield is the Hanging Temple built into a cliff face near Mount Heng. Most of the historical sites in this region date to the Tang and Ming dynasties, but the Hanging Temple dates to the Northern Wei dynasty.
The railway locomotive works began to attract increasing numbers of railway enthusiasts from the 1970s. When construction of steam locomotives was phased out, the authorities did not want to lose this valuable tourism market, and pondered the possibility of developing a steam railway operating centre as an attraction. A number of study visits were undertaken to the East Lancashire Railway at Bury, and a twinning arrangement was concluded with that town.
In 2010, work began on reconstructing the city's 14th century Ming dynasty defensive wall. The controversial reconstruction project was in its final phase at the end of 2014. The documentary The Chinese Mayor documents two years of vigorous and highly controversial effort by Mayor Geng Yanbo to push the reconstruction project forward.

Due to its strategic position it is also an important distribution and warehousing center for Shanxi, Hebei and Inner Mongolia.
Datong is an old fashioned coal mining city, and still sits on significant reserves of this commodity. Consequently, it has developed a reputation as one of China's most polluted cities. The Datong Coal Mining Group is based here and is China's third largest such enterprise. Datong is indeed however an emerging economy, as the city seeks to loosen its dependence on coal, introduce more environmentally friendly and efficient methods of extraction and move into other areas of business services. Local government has continued to upgrade its pillar coal sector, while also developing "substitute industries" such as machinery manufacturing, tourism and distribution, warehousing and logistics services. This has had some impact. Datong's GDP grew by 5.1 percent in 2008 to RMB56.6 billion.
While coal will continue to dominate, Datong has been identified as one of the key cities requiring redevelopment, with part of this being in environmental cleanup, rehabilitation and industrial refocusing. Datong is a pilot city for rehabilitation studies following years of pollution. To this end it has already struck up strong relationships with other cities worldwide with similar backgrounds, and has begun plans, for example, to develop a tourism base focused on steam engine technology with antique locomotives to be used along designated tracks.
Datong has a large railway locomotive works 'Datong locomotive factory', where the 'Aiming Higher' class of steam locomotive was built as late as the 1970s, steam locomotive production ended in the late 1980s and the plants main products is main line electric locomotives
