In 1173, builders broke ground in Pisa, Italy, on the Torre de Pisa (that is, the Tower of Pisa). At over 183 feet, it was to be a grand statement—remember, this was 1173, not 2016.
But the story is not all roses. The tower began immediately to tilt—by the time they started laying just the second floor of the tower, it was leaning. Thus, it earned the name we all now know (and love?), “Torre pendent di Pisa”—the Leaning Tower of Pisa. Wikipedia explains, “[t]he tower’s tilt began during construction, caused by an inadequate foundation on ground too soft on one side to properly support the structure’s weight. The tilt increased in the decades before the structure was completed, and gradually increased until the structure was stabilized (and the tilt partially corrected) by efforts in the late 20th and early 21st centuries.” The tower now leans over 12 feet from the vertical axis.
