The Sparta Rock House State Historic Site is a stone building near Sparta, Tennessee, United States, that once served as a rest stop and tollhouse. Built in the late 1830s, the Rock House catered to traffic along an important wagon road between Knoxville and Nashville, offering badly needed lodging and supplies to travellers who had just crossed the rugged Cumberland Plateau. The Rock House was added to the National Register of Historic Places in 1973 for its architecture and its historical role as an important rest stop.
