Wintrust Building

The Wintrust Building, located at two thirty-one South LaSalle Street, is identifiable by its neoclassical design and its position directly across from the Federal Reserve Bank of Chicago. Designed by the architectural firm Graham, Anderson, Probst and White, it was completed in nineteen twenty-four as the Illinois Merchants Bank Building. The structure holds an eighty-eight thousand square foot grand banking hall, an ornate interior space that once prompted architect Louis Sullivan to joke that the bankers working there should wear togas and speak Latin.
