What and Where Is Xi’an?

Xi’an is the capital of Shaanxi province, in north-central China, sitting at the center of the Guanzhong Plain between the Wei River to its north and the Qinling Mountains to its south [5][6]. With roughly 13 million residents across a metropolitan area of more than 10,000 square kilometers, it is the largest city in northwest China and a sub-provincial administrative, industrial and transport hub [5][6]. For most of its history the city was known as Chang’an; it took its current name, Xi’an, after the Ming dynasty [6]. Chinese provincial authorities describe it as the oldest of the country’s “Four Great Ancient Capitals,” alongside Beijing, Nanjing and Luoyang, with urban settlement stretching back more than 3,100 years [6].

Historical Origin and Development

Xi’an served as the capital of 13 Chinese dynasties over roughly 1,200 years, among them the Qin, Han and Tang [2][6]. Its rise to imperial prominence began with the Qin dynasty: in 221 BCE, Qin Shi Huang unified China’s warring states for the first time under a single centralized government and took the title of First Emperor [1]. He is buried in a vast mausoleum complex about 35 kilometers northeast of the modern city. Work on the complex began in 246 BC, as soon as he took control of the Qin state, and continued for 39 years, using a workforce that the historian Sima Qian put at roughly 700,000 [9].

Imperial Capital of the Han and Tang Dynasties

The city reached its greatest extent and influence under the Han and Tang dynasties, when, together with Luoyang, it functioned as the central capital of China and stood at the eastern end of the Silk Road [2]. Along that network of routes, goods, religious ideas, scientific knowledge and artistic styles moved between China and Central, South and West Asia from roughly the second century BCE to the sixteenth century CE [3].

Culture, Character and Economy

Xi’an’s modern economy extends well beyond its historic core. The city’s regional GDP reached roughly 1.2 trillion yuan (about US$167 billion) in 2023, up 5.2 percent year on year, with its tertiary (services) sector generating the largest share of output ahead of industry and agriculture [5]. The city is also a national center for aerospace and defense research: provincial officials report that Xi’an hosts more than a third of China’s domestic aerospace and weaponry research institutes and close to a quarter of its aeronautical research institutes, supporting a large civil-military manufacturing sector [6]. It is a major center of higher education, with 63 universities and colleges, seven military academies and more than 40 graduate training institutes [6], and it ranks among the country’s principal aviation and transport hubs [6].

Landmarks and Heritage Sites

The Terracotta Army and the Mausoleum of the First Qin Emperor

Xi’an’s most famous monument lies outside the city proper, near Lintong: the Mausoleum of the First Qin Emperor, inscribed on the UNESCO World Heritage List in 1987 [1]. First uncovered in 1974, the site includes an army of roughly 7,000 individually modeled, life-size ceramic soldiers, generals and horses, arranged in battle formation across three underground pits alongside real weapons and bronze chariots [8][10]. Research published in the journal Antiquity has reconstructed how the figures were produced: workers mixed local loess clay with sand tempering from alluvial deposits near Mount Lishan, then fired the pieces in kilns, under what the researchers describe as a highly organized system of centralized clay processing feeding distributed local workshops [8]. UNESCO recognizes the complex, which covers 56.25 square kilometers and contains more than 600 associated archaeological sites, for its artistic achievement, its documentary value for Qin-era military organization, its architectural relationship to the ancient Qin capital of Xianyang, and its commemoration of China’s first territorial unification in 221 BCE [1].

The City Wall and Silk Road Sites

Within the city, the Xi’an City Wall is among the most complete surviving Ming-dynasty fortifications in China. Built between 1370 and 1378 under a decree from the Ming founder Zhu Yuanzhang, it extended earlier ramparts from the Sui and Tang dynasties and the Yuan-dynasty Fengyuan City, and it runs 13.74 kilometers around the old city center; it underwent major restoration in 1983 and now appears on UNESCO’s tentative list as part of a proposed nomination of Ming- and Qing-dynasty city walls [4]. Several Xi’an sites also belong to the UNESCO-listed Silk Roads: the Routes Network of Chang’an-Tianshan Corridor, inscribed in 2014. China’s State Council highlights the Giant Wild Goose Pagoda, the Small Wild Goose Pagoda and the Daming Palace site among Xi’an’s heritage locations within that corridor [7], which more broadly runs from Chang’an and Luoyang westward across the Hexi Corridor and into Central Asia [2][3]. The Bell Tower, at the center of the old walled city, is also commonly listed among the city’s landmarks [11].

What Xi’an Is Best Known For

Internationally, Xi’an is known above all for the Terracotta Army and for its historical role as the eastern terminus of the Silk Road, the point of departure for the Han-dynasty mission of the envoy Zhang Qian that helped open overland trade between China and Central Asia roughly 2,000 years ago [7]. Within China, it is known as one of the country’s oldest and longest-serving imperial capitals [6].

Why Xi’an Matters

Xi’an matters because its archaeological record, anchored by the Qin mausoleum and set within the wider Silk Road corridor, documents both the formation of the first unified Chinese state and the trade networks that connected China to the rest of Eurasia for more than a millennium [1][2][3]. That depth of history now sits inside a large, functioning metropolis that anchors aerospace research, higher education and manufacturing for inland northwest China [5][6], making Xi’an one of the few ancient capitals in the world that remains a first-tier economic center in its own right rather than a preserved relic of one.
