The Frank L. Smith Bank, also known as the First National Bank of Dwight, is a bank building in Dwight, Illinois, United States that was designed by American architect Frank Lloyd Wright. Wright's earliest designs for the building date to 1904, but it was constructed in 1905 and opened in 1906. The design of the bank building deliberately rejects the classical influences common at the time, and is meant to evoke an air of simple dignity.
