Sebastian County Courthouse/Ft. Smith City Hall, Art Deco courthouse and city hall in Fort Smith, United States.

The Sebastian County Courthouse stands as a four-story stone and concrete structure on South 6th Street with marble walls and terrazzo flooring throughout. The building continues to house county operations while city offices relocated to a newer facility on Garrison Avenue.

Built in 1937 with Public Works Administration funding, the structure was designed by architects E. Chester Nelson and Bassham & Wheeler. It emerged as part of a broader program to create public employment during the economic downturn of that era.

The interior displays marble surfaces and ornamental details that reflect design preferences from the 1930s. When you walk through, the formal spaces show how public buildings were meant to impress visitors with fine craftsmanship.

The building sits on South 6th Street and remains active for county business. Visitors should know that certain city functions have moved to other locations, so check ahead if you need specific services.

The building's name reflects a shared arrangement: it served as both the Sebastian County courthouse and Fort Smith's city hall. City offices later moved to Garrison Avenue, but county facilities remain at 100 South 6th Street. It was added to the National Register of Historic Places in 1993.
