The Battle of Pea Ridge holds the notoriety of being the only battle in which Cherokees joined the Confederate troops against Union forces. The mill was reconstructed in 1867.

The architect decided to restore the historic structure and add a new wing of thirty rooms to the east. The new wing bridges across the auto entry and connects to the historic structure on the second level.

The interior of the mill was opened to create a three-level lobby. The top-level suites have internal balconies which view the entire three-story space through a structural grid of black walnut posts and beams.

Green marble marks the traditional building while a checker-board pattern of carrara and travertine marble designates the new structure.

The Inn at the Mill embraces a historic landmark listed on the National Register of Historic Places, formerly known as the Johnson Mill. This historic Inn is the first project that architect James Lambeth designed utilizing an existing structure.

First legally registered as a tax-paying business in 1835, the mill has the distinction of being the longest running business in the state of Arkansas, and possibly the longest continually operated mill in the nation.

Following the Civil War battle of Pea Ridge, Arkansas, in 1862, the mill was partially burned down by retreating Confederate renegades to prevent it from falling into the hands of the Federal forces.
