The Spring Street Historical Museum's building was constructed in the 1860s as Tally's Bank and is one of the oldest remaining buildings in downtown Shreveport. The building retains one of Northwest Louisiana's few remaining examples of New Orleans-style cast-iron gallery grillwork. The original bank vault and door are located on the ground floor. Since 1976, the building has been owned and operated by the Shreveport Committee of the National Society of Colonial Dames in Louisiana who oversaw its restoration and placement on the National Register of Historic Places. The Spring Street Historical Museum currently operates under the Secretary of State's Museum Program. The first floor of the museum features a transportation and historic maps. The second floor parlor exhibits traveling costumes.
