The Chicago Fed is one of 12 regional Reserve Banks that--together with the Board of Governors--make up the Federal Reserve System, our nation's central bank. One of its many responsibilities is making sure that there is a sufficient supply of U.S. currency in good condition. They oversee the Seventh Federal Reserve District, which includes all of Iowa and parts of Illinois, Indiana, Wisconsin and Michigan. The building's most recent renovation, started in 1986, upgraded its existing 820,000 square feet and included a 165,000-square-foot, 14-story addition. The Money Museum, on the first floor, opened to visitors in 2001.
