American architect builds dreams under Great Wall

Walking along the Great Wall is a once-in-a-lifetime dream for many, but Jim Spear has taken it one step further, spending the last 18 years living in a village beneath the ancient wonder.

"As a boy, I didn't know much about China, but I did know there was a Great Wall," says the 68-year-old, a self-taught architect from the United States. "Never did I dream back then that I would have the chance to visit it, let alone live under it."

One of the symbols of China, the Great Wall is actually a series of interconnected walls that extend for a total of 21,000 kilometers, some of which are 2,000 years old.
