Adena Mansion Restoration

photo of the Adena Mansion ""Adena," a name given to "places remarkable for the delightfulness of their situations."

--- Thomas Worthington
Diary Entry, Sept. 18, 1811

Portrait of Thomas Worthington links to Ohio Pix database page, AL02661 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.

Situated on the 300 remaining acres of the original homeplace are five outbuildings and formal gardens. The gardens have undergone major renovation. 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 was the inspiration for the Great Seal of the State of Ohio.

A new Museum and Education Center features interactive exhibits that use the stories of people connected to Adena to give visitors a picture of life in Ohio in the early 1800s as well as classrooms, meeting and rental space.

The mansion tour is guided; each group will be given a mansion tour time upon arrival. The Museum and Education Center, farm community and garden tours are assisted.
