Winnemucca City Hall (Winnemucca Post Office)

The one-story brick city hall was originally Winnemucca's post office and federal building. The city had fought for many years to acquire a federal building and finally, with the help of Nevada's U.S. senators, received a post office in 1920. Designed by the Office of the Supervising Architect of the Treasury, the building is small but refined, with a symmetrical facade receding slightly behind a projecting central section. The main entrance is embellished with a fanlight and flanked by two small multipane windows. A plain wood entablature has a simple frieze, a cornice with dentils, and a low parapet. An addition, designed by Louis Simon, the Supervising Architect of the Treasury in the late 1930s and early 1940s, nearly doubled the size of the building.

In 1942 Polly Duncan painted a mural, Cattle Round-up, on the north wall of the lobby. It depicts cowboys guiding cattle into a shed, while in the distance other cowboys drive in the rest of the herd from a broad valley framed by mountains. Like the post-office murals in Lovelock and Yerington, this one was painted under the auspices of the Treasury Department's Section of Fine Arts. The agency encouraged artists to work in a realist style and use themes relating to local history and customs. In 1991 the city of Winnemucca acquired the building, which became the city hall the following year.
