Boone County Courthouse was built between 1909 and 1911 in Lebanon, Indiana. It was listed on the National Register of Historic Places in 1986. The three-story Classical Revival structure of granite and Bedford limestone replaced earlier county court facilities on the site.

Inside, white Italian marble wainscoting and green Vermont marble bases line the walls in a carefully designed arrangement. The four-story rotunda with its stained glass dome creates an open, grand space that catches visitors' attention as soon as they enter.

County Circuit Court and Superior Court of the 12th Judicial District operate in the west side of the third floor. Visiting on weekdays during business hours gives you the best chance to see the courtrooms and administrative spaces.

The four Ionic columns of the porticoes measure 35 feet 3 inches (10.74 m) tall; at the time of construction they were among the tallest solid columns in the United States. Each was cut as a single piece rather than built up in drums.
