The Citizens-Union Savings traces its origin back to 1851 when it was established in what was then Tiverton, Rhode Island. In 1862, the state line was moved, and the bank obtained a Massachusetts charter. It moved to its current location in 1872, occupying the same building as the Pocasset National Bank. A new building was constructed in 1921, but was destroyed in the Great Fire of 1928. The contents of the vault were saved. The bank was soon rebuilt, opening in August, 1929. Fall River, Massachusetts.
Added to the National Register of Historic Places in 1983 as part of the Downtown Fall River Historic District (#83000662).
