Oak Ridge's inhabits won't let go of the past. But with a past this cool, who'd want to let go?

Juxtaposed against Oak Ridge's outdoor beauty is the city's fascinating World War II-era heritage that draws visitors from all over the world who want to touch a piece of U.S. nuclear history.

Originally cloaked in atomic secrets, Oak Ridge has emerged as a beautiful destination that has preserved its history while moving into the future as a training ground for world-class athletes.
