Capping the end of LaSalle Street and all of its neoclassical buildings is the imposing art deco tower of the Chicago Board of Trade. Built in 1930 by Holabird and Root, this is the second Board of Trade building to be constructed on the site. (Its predecessor, was designed by William W. Boyington in 1885 when traders' needs outgrew the building's space.) High atop the building is a statue of Ceres, the Roman god of wheat, glorifying the largest futures market in the world. Due to heightened concern regarding terrorist attatcks, the CBOT Visitor Center is closed to the public, however pre-arranged visits are available.
