Known to all in town simply as the ‘Duomo,' the Cathedral of Santa Maria del Fiore, with its neo-gothic façade in white, green and red marble, Brunelleschi's amazing dome and Giotto's imposing bell tower, is probably the first place visitors to Florence go. Just in front is the octagonal Baptistery of St. John, with its three unique sets of bronze doors, including those on its eastern side, which Michelangelo called the 'Gates of Paradise.' Inevitably, in circling the Baptistery, visitors will walk past a white marble column on a base of three stairs. It has a cross on top, with an unusual bronze relief underneath it. Overwhelmed by the magnificence of the other monuments in the square, few give the column more than a passing glance.
