Adena was the 2000-acre estate of Thomas Worthington (1773-1827), 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 houses designed by Benjamin Henry Latrobe still standing in the country. Latrobe is considered the first professional American architect and served as architect of the U.S.capitol under President Thomas Jefferson.
