Wintrust's Grand Banking Hall
The Central Standard Building
231 S. LaSalle St.
Graham, Anderson, Probst & White, 1924
The Central Standard Building, formerly the Continental Illinois Bank Building, stands across LaSalle Street from the Federal Reserve Bank of Chicago, two neoclassical near-twins guarding the main intersection of Chicago's financial district. Interior spaces include a mix of neoclassical and Gothic Revival architecture with Art Deco influences, most notably a massive 88,000-square-foot grand banking hall on the second floor, recently restored. The building stands on the site of the former Grand Pacific Hotel, where the continental United States was officially divided into four standard time zones in 1883, an event commemorated by the building's name and a plaque on Jackson Street.
