History of Crook County Courthouses: The first courthouse was a one story wooden structure at the corner of West 5th and Main Streets. In 1885 a two story wooden structure was built for $5,474. By 1905 this building was considered unsafe to store the county's records, and a $16,526 bid was accepted to erect a new, brick and stone courthouse. The historic courthouse building was completed in 1909, at a cost $48,590.
The newly constructed 'Crook County Justice Building' which houses the courthouse was completed in October of 2024 with county and state funding.
