The dramatic stone mansion on a hill north of Chillicothe, Ohio, was the home of Thomas and Eleanor Swearingen Worthington and their ten children. Thomas Worthington (1773-1827) was one of Ohio’s first U.S. senators (1803-1807) and there he lobbied for Ohio’s statehood. He served in the Ohio statehouse from 1807-1808, and again in the U.S. Senate from 1811-1814. He served as the sixth governor of Ohio (1814-1818). In 1818, Worthington stepped away from politics for a time and reinvested his energies in his numerous business enterprises, including farming, milling, land surveying, river shipping and construction of river canals. 

The Worthingtons planted extensive gardens around the home including a fruit tree orchard, grape vines and plots for vegetables. Once the grounds served as a dramatic setting for outdoor walks and soirees. The gardens have undergone major renovations, and the gardens at Adena have again becoming a focal point for the public to have a view into the lifestyle lived in the early nineteenth century. Visitors may stroll through three terraces of flowers and vegetables, as well as see trees in the grove.

Adena Mansion and Gardens is managed locally by the Adena Mansion & Gardens Society.
