Built along the Nanxi River, between the steep mountains of China’s Yunnan Province, Yanjin county is widely regarded as the world’s narrowest city.
Looking at Yanjin county from above, it’s hard to believe that such a settlement actually exists in real life. The narrow stretch of usable land sandwiched between the troubled waters of the Nanxi River and steep mountains on either side hardly seems like a suitable location for a city of roughly 450,000 people, but that’s exactly what makes Yanjin so special. It looks more like something you’d expect to see in a fantasy movie, or in a building simulation game than a modern-day city.
