Founded in 1794, this is Tennessee's oldest college, the nation's 28th oldest, and the oldest co-ed Presbyterian-affiliated school in the world. Samuel W. Doak, son of Presbyterian minister and Washington College Academy founder Samuel Doak, started this 140 acre campus, later named Tusculum College. During the Civil War, its buildings served as barracks for soldiers. Today, this private college has around 1,500 students and in addition to its main campus, maintains a regional center for studies in Knoxville, and satellite campuses across East Tennessee.
