The building was listed on the National Register of Historic Places in 2000 as the United States Post Office and Courthouse.

[2] The federal building was constructed on a site that was occupied by five simple wood-frame houses on the western edge of the center of town adjacent to several churches and hotels of quality architecture.

The building was designed as a United States Post Office and Courthouse (original name) and functioned as a complete federal center for the region.

The building is set back with granolithic paving, granite steps, grass and shrubs fifteen feet from the sidewalk on three sides.

The landscaping and steps are contained by a low concrete wall that connects stone pedestals which support cast iron lamps.

[3] The facades of the building are composed with elements of both the Second Renaissance Revival and Neo Classical styles and were designed to be symmetrical about both axes.

The front elevation (east) is organized around a central three story decastyle of engaged (pseudo-peripteral) Corinthian columns which rise from the building base.

The end elevations are designed similar to the front but are organized around five bays defined by pilasters rather that the engaged fluted columns.

There are carved stone panels bearing governmental seals above the entryways and on the flanking bays of the front facade at the fourth floor.

The lobby as it currently exists has been severely compromised by the removal of much of the original, and ornate high quality material, and the infill of average office space at the north and south ends.

The center entry is flanked by two marble stairways with heavy carved wood balustrades that extend to the forth floor.

The courtroom features stained wood wainscot, built-in court furnishings, and cast bronze wall sconces.

[3] In 1937 the U.S. Treasury, with Louis A. Simon as supervising architect, designed the primary addition to the west side of the building.

The frame was supported by brick and stone exterior walls and was entirely fireproofed with concrete which was also used for the floors and footings.
