Completed in 1841 when Florida was still a territory, the Union Bank is the state's oldest surviving bank building. Chartered to help finance local cotton plantations, it ultimately closed because of crop failures, the Second Seminole War, and poor management. After the Civil War, it reopened as the Freedman's Savings and Trust Company for emancipated slaves and later served several other functions. In 1971, the Bank was moved from its original site, and, after restoration, it was opened as a museum in 1984. The Union Bank now serves as an extension of the Florida A&M University Black Archives, Research Center, and Museum and is open to the public and school groups only on weekdays. Artifacts and documents reflecting black history and culture are on display, and public programs are provided by Black Archives staff.

The bank offers exhibits.
