First National Bank, Historic bank building in Columbus, United States

First National Bank, known locally as the Iron Bank, is a cast iron office building at 1048 Broadway in Columbus, Georgia. Its cast iron front and cast iron cage were shipped from New York and Pittsburgh. The building was erected for the Bank of Columbus at a cost of $50,000.

The Bank of Columbus built this cast iron office building in 1860 at a cost of $50,000 and used it until 1866, when the bank apparently went bankrupt. It was then bought at auction for $28,000 by the Georgia Home Insurance Company. Various banks have used it since, including the First National Bank of Columbus in 1974, the year it was listed on the National Register of Historic Places.

The building is known locally as the Iron Bank because of its cast iron facade, which was brought from northern cities. Locals continue to call it this way when they talk about the place.

The building remains in active use and can be viewed from the outside, with its architectural details clearly visible from street level. Its central location makes it easy to reach while exploring the downtown area.

The building appeared on a 50-cent note issued by the local bank, which is now a rare collectible item. This currency shows how central the structure was to the city's financial identity.
