The Town Square Museum is located in the historic US post office near the county courthouse. This space is used to house and display Pontotoc memorabilia. A full-service post office continues to operate in the building, which was built in 1937 during the Great Depression. It was one of numerous projects of the Works Progress Administration (WPA) under President Franklin D. Roosevelt. Investment in this program created work opportunities in construction of needed public buildings and infrastructure across the country, employing thousands of workers.
