The building is an example of Renaissance Revival architecture, symmetrical in form and with all four facades treated in the same manner.
As the community grew and the post office expanded, there arose a need for additional postal service space.
The building was listed on the National Register of Historic Places in 1977 as part of the Downtown Commercial District.
It is significant to the district as an example of Renaissance Revival architecture and as a symbol of the federal presence in the community.
Courthouse in Bowling Green, Kentucky, is a three-story Renaissance Revival white limestone building with a rusticated base.
The central door opening at the original east elevation entry is more ornate including a transom which is detailed with high relief carvings of an American spread Eagle resting on a bracketed cartouche.
The two central first floor apertures of the 1912 building are set within recessed limestone surrounds with radiating voussoirs and keystones.
Though the lobby has been significantly altered, it retains the plaster panel ceiling, marble wainscot, and a mural on the south wall.
It begins as a double return stairway leading to a mezzanine landing where it winds into one central stairwell at the second floor level.
