Dickson Co. Courthouse Tower - Charlotte, TN
The Dickson County Courthouse in Charlotte, TN is the oldest courthouse in the state still in use, built in 1830. (The Hawkins Co. Courthouse in Rogersville also makes this claim citing how this courthouse has been changed and expanded while theirs hasn't, albeit not quite as old.)
This mural depicts the way the courthouse looked back then, with some noticable changes from today. Wings were added on both sides in 1931. The chimneys were removed and the roof, and shutters and dome on the tower are now white instead of red.
