The Golden Lamb Inn is the oldest hotel in Ohio, having been established in the Warren County seat of Lebanon in 1803. The present three-story structure is built around the 1815 rebuilding of the inn. In 1926 it was purchased by Robert Jones, grandfather of congressman Rob Portman, who refurbished it and decorated it with Shaker furniture. It was known as the Golden Lamb because that image appeared on its signboard for the benefit of the illiterate. At various times it has been known as the Ownly Hotel, the Bradley House, the Lebanon House, and the Stubbs House.

Because of Lebanon's position on the highway between Cincinnati and Columbus, many notables have visited. The inn has been visited by ten American presidents: William Henry Harrison, Benjamin Harrison, John Quincy Adams, Martin Van Buren, Rutherford B. Hayes, James A. Garfield, William McKinley, Warren G. Harding, William Howard Taft, and George W. Bush. Other famous travellers to have stopped there include Charles Dickens, Thomas Corwin, Clement Vallandigham, Cordell Hull (who went to school in Lebanon), Robert A. Taft, and Dewitt Clinton.
