The Grand Ole Opry played Nashville's Ryman Auditorium for over 30 years, until 1974, when the show moved to a new building. Workers cut a six-foot circle of oak from the old stage and inlaid it dead center in the new one. Every performer since has stood on that circle to sing. In 2010, a flood swamped the entire stage. The circle was dried out and put back in place. It's still there today.
