Architect Nelson Strong Spencer designed the courthouse in a mix of the Classical Revival and Beaux-Arts styles.
The front entrance features a pediment and entablature supported by four columns, all designed according to the Doric order.
A parapet and a terrace with balustrades along the sides, both among the building's prominent Beaux-Arts elements, line the roof.
In addition to its government functions, the courthouse has hosted large community events and serves as the focal point of downtown Murphysboro.
