The Torre dell’Orologio – Clock Tower – stands above the arch leading to the Mercerie shopping street close to the Basilica. Built at the end of the 15th century, its brilliant clock-face and its digital clock are linked with automata, which attract crowds to the Piazza. On the summit of the tower two large bronze figures known as the Mori (Moors) strike the hour. During Ascension Week and at Epihpany, figures of the Magi emerge to either side of the clock-face and bow to the statue of the Madonna above it.
