Andrew Johnson National Historic Site is the reason Greeneville matters to most visitors. The park links Johnson's tailor shop, early home, homestead, museum exhibits, and grave, turning a few downtown blocks into a compact biography of one of the most difficult presidencies in American history.
The tailor shop is the most vivid piece: a small workingman's building preserved inside a later memorial structure. It makes Johnson's rise from trade to president feel less abstract than a textbook summary ever could.
