 In 1895, the clock tower was removed and the "tallest building in Chicago" record was then held by the tall Masonic Temple Building.Built on caissons surrounded by muck, the trading house was rendered structurally unsound in the 1920s when construction began across the street on the Federal Reserve Bank of Chicago.The 1885 building was subsequently demolished in 1929, and the exchange temporarily moved to Van Buren and Clark while a new building was constructed at the LaSalle and Jackson site.
