Located behind the courthouse in Loudon  is one of the area's oldest homes. The Carmichael Inn is a two story log structure which served as a stopping place for stage coach travelers enroute from Nashville, Knoxville, and Chattanooga. Travelers would be ferried across the river to spend the night and then resume traveling the next morning by the next stagecoach. Although the exact date of construction is unknown, the first stage of construction is thought to have been completed around 1810. The log house was built by John Hudson Carmichael (1780-1840). His sons operated the Inn, the ferry, and the stagecoach. Two of his sons, James and Dan, fell in love with and married two sisters who were traveling on the stagecoach from Georgia to the Tate Springs Resort.

      The Carmichael Inn can be described as an "I-house" as it is two stories tall, one room deep and two or more rooms long. It has a central chimney which opens into fireplaces in the two downstairs. The structure has a gable roof and two front and two rear doors. A two-story porch runs the length of the house. The Carmichael Inn is currently being used as a museum and visitors center.
