Adena Mansion & Gardens Historic Site 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, completed in 1806-1807, has been restored to look much as it did when the Worthington family lived there, including many original Worthington family furnishings. The house is one of only three designed by Benjamin Henry Latrobe still standing in the country. Latrobe is considered the first professional American architect and served as the architect of the U.S. capitol under President Thomas Jefferson.
Five outbuildings and formal gardens are situated on the 300 remaining acres of the original home place. The gardens have undergone a major renovation. Visitors may stroll through three terraces of flowers and vegetables and 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 inspired the Great Seal of the State of Ohio.
