The Manhattan Project

With the hope of developing technology that would end World War II, the U.S. government built Oak Ridge under a cloak of great secrecy. In 1942, the U.S. Army Corps of Engineers purchased land that would become Oak Ridge, the first and largest of the three Manhattan Project sites that were built to produce the world’s first atomic weapons. Inside top-secret plants located in valleys near Oak Ridge, scientists and workers used two methods, and then eventually three, to produce fissionable material needed to develop atomic bombs.

The Secret City

When the Japanese attacked Pearl Harbor on Dec. 7, 1941, the city of Oak Ridge didn’t even exist. In an effort to end the war, the U.S. government purchased rural farmland in 1942 and rapidly built the city of Oak Ridge, which would play a pivotal role in the Manhattan Project. Just two and a half years later, the Secret City skyrocketed to a population of 75,000, making it the fifth-largest city in Tennessee at the time.

John Hendrix Memorial Prayer Walk

The John Hendrix Memorial Prayer Walk is an easy half-mile historic nature trail, which tells the story of John Hendrix. According to local legend, Hendrix was just an ordinary farmer until he started having visions in 1900 about the future of Bear Creek Valley, which became Oak Ridge. After sleeping in the woods for 40 days and nights, Hendrix apparently had a vision that “Big engines will dig big ditches, and thousands of people will be running to and fro. They will be building things, and there will be great noise and confusion, and the earth will shake.”
