Mono County, California (Map It) was created on April 24, 1861 primarily from Calaveras County, Fresno County, and Mariposa County . Mono County was named for Mono Lake, which, in 1852, was named for an Indian tribe that inhabited the Sierra Nevada from north of Mono Lake to Owens Lake. The tribe’s western neighbors, the Yokuts, called them monachie, meaning “fly people,” because the pupae of a fly was their chief food staple and trading article.

Old Mono County Courthouse
Courthouse History - After a survey of state boundaries, in 1863 citizens of Mono were alarmed to learn that their county seat, Aurora, lay three miles inside the Territory of Nevada. It was reported that upon hearing the news, the presiding judge immediately closed the court and announced that he would try no further cases there. Voters selected Bridgeport as the new center of government and built a landmark Italianate building that remains in use as one of the state's oldest operating courthouses. The courthouse is listed on the National Register of Historic Places.
