One of the most beloved buildings in Chicago sits at the southern end of the LaSalle Street canyon. The Chicago Board of Trade (CBOT) Building is on the same site as an earlier Chicago Board of Trade Building from 1885. Completed in 1930, the imposing Art Deco structure was the tallest building in Chicago for 35 years until surpassed by the Richard J. Daley Center. It is notable for its 30-foot-tall statue of Ceres, the goddess of grain, and its stunning multi-story lobby. An expansive vault in the basement has sat empty for decades, making this forgotten cavern an attraction unto itself. Built by the Chicago Board of Trade Safe Deposit Co., the vault has secured many different items of importance throughout its long history, such as trading receipts, silver bars and thousands of steel lock boxes.
