After breakfast, begin your visit to Jiaohe Ancient City (交河故城), one of the best-preserved ruins of ancient cities along the Silk Road and inscribed on the UNESCO World Heritage List as part of the joint application "Silk Roads: the Routes Network of Chang'an-Tianshan Corridor." Jiaohe Ruins offers a profound glimpse into ancient city planning and the historical complexity of the civilizations on the Silk Road.
Nestled between two deep river valleys, Jiaohe, meaning "the confluence of two rivers," is strategically positioned on a large, steep plateau that provides formidable natural defenses. As a key city connecting the Central Plains (中原) and the vast regions of the Western Regions (西域), Jiaohe Ancient City played a vital role in the transportation network of the Silk Road. It witnessed the bustling trade along the Silk Road and the exchange and integration of Eastern and Western cultures.
Unlike many ancient cities, its structures were not built up from the ground but carved down into the existing plateau of loess soil. Walking through the ruins, you can see the remains of government offices, residential houses, Buddhist stupas, and temples. These remnants not only provide important physical evidence for studying the history and culture of the Silk Road but also offer valuable insights into the social, economic, and religious life that shaped this region. Tips: There is no shelter inside the ruin, so be mindful of sun protection.
The History of Jiaohe Ancient City
The Ancient City of Jiaohe witnessed the development of civilization in the Western Region and the Silk Road. Approximately 2,000 years ago, it was established as the capital of the Jushi Kingdom (车师国), one of the 36 kingdoms in the Western Regions (西域三十六国). Following Zhang Qian's pioneering efforts during the Western Han Dynasty to carve a path through the Western Regions, Jiaohe City emerged as a crucial hub on the Silk Road. In 60 BC, the Han Dynasty central government established the Protectorate of the Western Regions (西域都护府) to administer the various states in the region, officially incorporating the Western Regions into the Chinese domain. During the Northern and Southern Dynasties, Jiaohe became a county under the jurisdiction of Gaochang(高昌). The city reached its zenith during the Tang Dynasty with the establishment of the Anxi Protectorate (安西都护府), marking a new era in the governance of the Western Regions. During this period, Jiaohe was a bustling center of international trade and vibrant cultural exchanges among diverse ethnic groups. From the 19th to the 14th century, due to the impact of wars, Jiaohe gradually declined and eventually became a ruin.
Next, head to the Karez System (坎儿井) to learn about the ancient underground irrigation system a few thousand years ago and how this system has benefitted the people along the desert's edge, transforming barren land into a lush oasis. This traditional engineering marvel is considered one of China’s three great ancient engineering projects, alongside the Great Wall and the Grand Canal. It has been recognized in the 2024 World Irrigation Project Heritage list.
The origin of the Karez Irrigation System
Turpan, in Xinjiang, is one of China's most arid regions, with annual rainfall of only 16 millimeters and evaporation exceeding 3,000 millimeters. These extreme conditions have led to severe surface water scarcity. To improve their survival prospects, people ingeniously utilized the natural slope of mountains to channel underground rainwater, glacial melt, and snowmelt from spring and summer to the surface for irrigation. This method greatly reduced water loss through surface evaporation, meeting the water needs of this arid region. It’s often said, "Without the Karez, there would be no Turpan; without the Karez, there would be no civilization in Turpan." The Karez has turned extremely arid basins into green havens, making Turpan a crucial corridor for East-West exchanges along the Silk Road and a place where diverse cultures converge and coexist.
The Karez system is often referred to as the "Underground Great Wall". In Xinjiang, there are over 1,700 karez wells which, if connected, would stretch over 5,000 kilometers, forming a vast underground river network. It is estimated that the Karez system has a history of over 2,000 years. Imagine centuries ago, without modern measuring tools or mechanical assistance, how ancient people located underground water sources, determined the gradient and direction in complete darkness, and connected such lengthy channels. Today, you have the opportunity to step into the Karez and personally unravel the secrets of this most mysterious hydraulic engineering project, experiencing first-hand how ancient innovation works.
Next, continue your exploration at the Emin Minaret (额敏塔), the tallest Islamic minaret in Xinjiang. Also known as Sugong Ta (苏公塔), this remarkable structure was erected in 1778 by the local ruler Suleiman, in tribute to his father, Emin Khoja, whose considerable efforts helped maintain national unity.
It stands 44 meters (144 feet) tall and is made from sun-dried bricks, which give it a distinct, earthy color. The tower's cylindrical body tapers elegantly as it rises, topped by an ornate, pointed dome. Uyghur artisans crafted up to 15 different types of brick patterns, including waves, diamonds, floral clusters, and crosses, which create endlessly looping designs around the tower. Gazing up from beneath the tower, you can fully appreciate the simplicity and grandeur of these designs. The accompanying mosque is an integral part of the complex, which you can visit as well. Emin Minaret serves not only as a religious structure but also as a cultural icon for the Uyghur people, embodying a unique blend of Islamic and Uyghur architectural traditions.
Afterward, return to Urumqi for an overnight stay.
