This weekend, the Secret City Festival returns to Oak Ridge.
The unique event combines the Manhattan Project's history and the city's role in World War II with things such as entertainment, arts and crafts. This is the 10th year for the festival.
You can tour some of the ORNL, Department of Energy and Y-12 facilities.
There's even a special WWII re-enactment Saturday.
"We're celebrating the history and heritage of Oak Ridge. We're bringing out all of our community members and lots of great exhibitors to celebrate and honor those people that were here during the Manhattan Project and really just show them that we appreciate what was done here and we want to celebrate what was done here, and be able to tell our future generations about the importance of Oak Ridge and this festival's a great way to do that," said Katy Brown, president of the Oak Ridge Convention and Visitor's Bureau.
