The Franklin County Courthouse, located in Courthouse Square on Main Street in Ottawa, is the seat of government of Franklin County, Kansas. The courthouse was built from 1892 to 1892; while Ottawa had been the county seat since 1864, it lacked a permanent courthouse prior to then. Architect George P. Washburn designed the courthouse in the Romanesque Revival style; the red brick courthouse is considered one of Washburn's "most outstanding works". The design features four square corner towers, a typical feature of Washburn's designs; two cupolas on the roof include a bell tower and a clock tower. The intricate roof design includes a main hipped roof with gable ends on each side and steep hipped roofs atop the towers. The roof line is ridged with a metal spine, and a dentillated cornice runs beneath the roof's edge. The east and west entrances to the courthouse are through large porches supported by brick columns and topped with balconies. The second-story windows are arched and connected by a band of stone.The courthouse was added to the National Register of Historic Places on March 17, 1972.
