""Adena," a name given to "places remarkable for the delightfulness of their situations."
--- Thomas Worthington
Diary Entry, Sept. 18, 1811
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.
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.
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

Adena experience has been developed to ensure that student visits are
fun as well as instructional. Students participate in hands-on activities
and learn of pioneer food ways, traditions, and the cultural practices
of the people who lived on the estate, including the formerly enslaved
individuals who accompanied the Worthingtons to Ohio.
Tours can be directed to any age level and any area of emphasis.
A complete tour includes the Museum and Education Center, farm community,
garden and mansion. 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. In order to experience the
complete tour, a minimum of three hours on site is recommended.
Limited lunch facilities are available. Students may wish to shop in
our Ohio History Store if time permits. Because our school tour schedule
fills rapidly, early reservations are encouraged.
