The old Mohave County Courthouse and adjoining jail are two of the most historically significant buildings in Kingman, listed on the National Register of Historic Places since 1983. The courthouse dates from 1915 and was the seat of county government during the period when Mohave County was being carved up by mining claims, railroad grants, and land speculation. The architecture is straightforward territorial style — brick, symmetrical, functional.
The buildings have been vacated as an active courthouse but are maintained as historic landmarks. The exterior is freely accessible and the scale of the complex gives a sense of how important a county seat Kingman was in the early twentieth century. The jail wing, in particular, is a reminder that the region's history was not always peaceful.
