Built in 1857 as Millville's first banking institution, chartered by the New Jersey legislature, this masonry building was expanded in 1883. After the bank moved to a larger site in 1908, the building became the Millville Library and Reading Room, later the Millville Public Library. Colonial Revival updates in 1942 replaced the front elevation doors and windows, and from 1963 through 1975 the city used the building as a Baby Keep Well Center, adding interior partitions and bathrooms. The Millville Historical Society began leasing the property in 1977 and restored it, using the original banking space as its archives and reading room. In 2009-2010, the standing seam metal roof was restored and a preservation plan was developed to guide restoration and ongoing maintenance. The building is historically significant as Millville's first chartered bank and as the long-time home of the public library, and architecturally significant as an unusual high-style example of Greek Revival with Italianate detailing. It was listed on the New Jersey Register of Historic Places in November 1976 and on the National Register of Historic Places in November 1980.
