The building is constructed of concrete-encased steel, with concrete slab floors and walls of terra-cotta brick, covered with plaster. The square shaped building has a center courtyard and the building covers the entire block. Along each side are columns. The roof line is flat. The interior of the building has four two-story courtrooms which feature most of the courthouse’s original design; some two-story courtrooms were split horizontally during the 1950s, expanding capacity and resulting in new floors. 


Note: The first courthouse was built in 1866 with additions in the 1880s. The courthouse was replaced by the current courthouse and, which was completed in 1914. Originally, the building had a central courtyard and over time, this courtyard was filled in to make room for more offices and a jury room.
