The Greek Revival style used for the Second Bank contrasts with the earlier, Federal style in architecture used for the First Bank of the United States, which also still stands and is located nearby in Philadelphia. This can be seen in the more Roman-influenced Federal structure's ornate, colossal Corinthian columns of its façade, which is also embellished by Corinthian pilasters and a symmetric arrangement of sash windows piercing the two stories of the façade. The roofline is also topped by a balustrade, and the heavy modillions adorning the pediment give the First Bank an appearance much more like a Roman villa than a Greek temple.
