A Romanesque building of rough hewn limestone designed by John Haskell and Frederick Gunn.
"The three and one-half story native stone Douglas County courthouse is basically rectangular in plan with slight irregularities caused by the clock tower, the stair tower, the gable ends and the entrance features. The exterior walls of the Romanesque structure are constructed of rough-hewn Cottonwood limestone laid in regular courses. A narrow band of smooth cut limestone runs entirely around the building at the first floor sill. A wide band of smooth cut limestone wraps entirely around the building at the first floor lintels.
The dominant feature of the courthouse is the square clock tower. Located on the west side just north of the main entrance, it rises six stories high and is terminated by a pyramidal roof, which in turn is capped by a metal finial. Four large minarets begin on the sixth floor and rise past the roof line, adding to the impressive character of the tower. At the fifth floor small corbelled out balconies with iron railings are placed on all but the east side. The clock in the tower is still in working order."
