The history of Jiayuguan is inextricably linked to its role as a strategic outpost on China's western frontiers. Although people have settled in this region since ancient times, the key moment in the city's history was the construction of the famous fortress, begun in 1372 during the Ming Dynasty. It was this powerful fortification, known as the "First and Greatest Pass Under Heaven," that gave birth to the city and defined its future destiny.
The rise of Jiayuguan was driven by several factors. Firstly, its unique geographical location: the pass was erected at the narrowest point of the Hexi Corridor, between mountain ranges, making it an ideal defensive point. Secondly, the city was a crucial link on the Great Silk Road, serving as a gateway for trade caravans travelling from China to Central Asia and back. This ensured not only military but also economic significance. Thirdly, the political will of the Ming emperors, striving to strengthen the empire's western borders, became the decisive force in creating and maintaining this outpost.
From the very beginning, Jiayuguan was not merely a military garrison but also a place of cultural and economic exchange. Passing through its gates were not only goods such as silk, spices, and precious stones, but also ideas, technologies, and religious teachings. The pass symbolized the boundary of the civilized world in the view of the ancient Chinese, beyond which lay boundless and dangerous lands. This status as the "Gate to the Desert" shaped a distinct culture and left a deep imprint on the region's history, making Jiayuguan one of the most significant historical monuments on the Great Silk Road.
