The former Post Office now houses the Internal Revenue Service
"The United States Post Office, located at 315 W. Pershing Road, Kansas City, Jackson County, Missouri, is a five-story reinforced concrete facility measuring 265 by 280 feet. Designed by James A. Wetmore, Acting Supervising Architect, United States Treasury Department and constructed in 1930-1933 by Ring Construction Company, Minneapolis, the Neo-Classical facility epitomized the urban design ideals adopted by the City Beautiful Movement. Although the main facade faces north, all facades are characterized by the same monumental design and embellishments in limestone. During the initial Federal appropriation for construction of the post office in 1916, the bill authorizing the purchase of the land in Kansas City also included language that established uniform plans for all post office buildings based on the size of the community served.
Located at the intersection of Broadway Boulevard and Pershing Road, the United States Post Office features a surface parking lot directly to the north of the building, while the National Register listed Union Station is located across Pershing Road slightly to the northeast. The Sweeney Building, a multi-story office building is sited to the east and to the west is the Royal Office Building. Penn Valley Park and Liberty Memorial, listed on the National Register of Historic Places, are located to the southeast. To the southwest on the east side of Broadway are one-story commercial buildings. The facility is sited on five-acres.
In excellent condition, the United States Post Office Building has retained the majority of its historic features to convey its historic significance."
