Fully renovated in 2015, the 88,000 square-foot Grand Banking Hall on the 2nd floor of the Central Standard Building stands opposite the Federal Reserve Bank of Chicago, two neoclassical near-twins guarding the main intersection of Chicago's financial district. The dramatic interior includes a mix of neoclassical and Gothic Revival architecture with Art Deco influences. The 1924 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.
