Wynnewood State Historic Site is at 210 Old SR 25. Built in 1828, the 142-foot-long log structure served as a stagecoach inn and mineral springs resort. The inn contains period furnishings, including the bed that Jesse James slept on during his stay at the inn.
Displays throughout the inn tell the story of the Wynne family who moved into the inn in 1834. A large detached kitchen used to prepare meals for inn guests is furnished in period. A small 1830s cabin once occupied by the local doctor is on the grounds.
Educational programs are offered the third Sunday of the month during the summer.
