Architect Mark Lemmon of Dallas designed this Art Deco U.S. Post Office building in 1935 during the New Deal.  Constructed of reinforced concrete, Stephenville’s Art Deco post office is two stories with a basement. The façade, or  east elevation along N. Columbia Ave., features five vertical strips of windows separated by vertical fluted panels. The  windows and center entryway are topped by spandrels decorated by geometric ornamentation. The entryway features a  double door topped by a large transom. Two large Art Deco-style metal lanterns flank the entryway. The post office  building has a flat roof that drains to the rear. The building is slightly set back from the sidewalk with landscaped  gardens, a walkway, and a center staircase. The rear, or west elevation, faces a parking lot and features a center  entryway under a small simple portico and an exterior chimney. In 1968, the U.S. government deeded the post office  building to the City of Stephenville and it is now home to the community’s library.
