The Rhea County Courthouse is a historic county courthouse in the center of Dayton, the county seat of Rhea County, Tennessee. Built in 1891, it is famous as the scene of the Scopes trial of July 1925, in which teacher John T. Scopes faced charges for including Charles Darwin's theory of evolution in his public school lesson. The trial became a clash of titans between lawyers William Jennings Bryan for the prosecution and Clarence Darrow for the defense, and epitomizes the tension between fundamentalism and modernism in a wide range of aspects of American society. The courthouse, now also housing a museum devoted to the trial, was designated a National Historic Landmark in 1976.
