Tree of Life

Photograph by Jeff Nelson , National Geographic Your Shot

Tourists flock to a lone tree along the path of Hadrian s Wall in northern England. Built between 122 A.D. and 128 A.D., the wall spans a 73-mile neck of land between the Tyne and the Solway Firth a solid northern boundary for the entire Roman Empire. It s often considered the most important relic of Roman rule in Britain.

"I wanted to get the photo without people, but that wasn't possible," says photographer Jeff Nelson . "In the end, I feel they give the photo better perspective."
