CNN praises Vietnam's 'Underground City': One of the most fascinating in the world!

On July 12th, CNN published a photo article titled "The World's Most Amazing Tunnels ," which included the Cu Chi Tunnels in Vietnam , which the Voice of Vietnam online newspaper called the "Underground City" and described as a unique "wonder."

With a tunnel system totaling 250km in length, the Cu Chi Tunnels contain a full range of structures such as trenches, food storage areas, kitchens, wells, living quarters, offices, and infirmaries, all interconnected like a spiderweb. This has made the Cu Chi Tunnels one of the six most unique man-made structures in the world, and also one of the seven most bizarre destinations in Southeast Asia.

Today, this unique structure has become a popular tourist attraction in Ho Chi Minh City, drawing visitors from both within and outside the country.

That's why CNN recently included the Cu Chi Tunnels in its list of the 20 most amazing tunnels in the world.

Let's take a look at these unique destinations through CNN's stunning photo collection:
