Incorporating elements from the Victorian commercial buildings at its base, this twenty-two-story tower may serve as a case of contextualism in response to historic preservation. A product of the postmodern era, the structure stands on a prominent site across from the South Station Transportation Center (FD26). Composed of gray granite, vertical glass strips, and cast stone, the tower rises like a gigantic column from its lower level of nineteenth-century, five-story brick and granite buildings. Its crowning pedimented aediculae are almost parodies of 1920s skyscrapers. A six-story brick ventilator shaft for the old Central Artery incongruously exists alongside. The lobby is a predictably luxurious space lined with multicolored marbles and opening to a flat-roofed rotunda.
