Adena was the 2,000-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 U.S. Latrobe is considered the first professional American architect and served as architect of the US capitol under President Thomas Jefferson. 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.

Unable to locate an official site to verify the continued existence of the house. Moreover, other sites which discuss the House of Voodoo paint it, first and foremost, as a commercial destination. Exhibits on voodoo and the history thereof are located within the back of an occult store.
