Ohio's Bicentennial

Adena, located in Chillicothe, Ohio, was the estate of Ohio's first United States Senator and sixth Governor, Thomas Worthington. The mansion, built in 1807, was designed by the first professional architect in the United States, Benjamin Latrobe. Adena was refurbished to resemble its early 19th century appearance and reopened to the public in 2003 to celebrate the Ohio Bicentennial.

In 2003, Ohio celebrated two hundred years of statehood. Festivities occurred across the state. The Ohio Bicentennial Commission had at least one barn in each of Ohio's eighty-eight counties painted with the bicentennial logo. The commission also had a bicentennial bell cast for each county and published a series of books on Ohio's history.

Other groups also actively participated in the celebration of Ohio's bicentennial. The Ohio Historical Society restored Adena, the home of Thomas Worthington. Worthington was one of the main supporters of statehood in 1803 and one of Ohio's first two United States Senators. The Ohio Bureau of Motor Vehicles created a special license plate to commemorate the Ohio bicentennial.
