Adena Was the 2000-acre estate of Thomas Worthington (1773-1827), the sixth governor of Ohio and one of the state’s first United States Senators. The mansion house was completed in 1807 and has been restored to look much as it did when the Worthington family lived there, including many of the original Worthington family furnishings.

The house is one of only three houses designed by Benjamin Henry Latrobe still standing in the country today.

Situated on the 300 remaining acres of the original home place are five outbuildings and formal gardens. The gardens have undergone major renovations. Visitors may stroll through three terraces of flowers and vegetables, as well as the shrubs and trees in the grove. Looking east from the north lawn of the mansion one can see across the Scioto River valley to the Logan Range. This view is the inspiration for the Great Seal of the State of Ohio.
