A unique landmark of Venetian architecture, St. Mark’s Clock Tower is part of a 15th-century building featuring the central tower thought to be designed by Mauro Codussi flanked by two shorter wings on either side. The clock mechanism has changed over time, with a later addition of panels with Roman numerals and Venice’s winged lion symbol, but the two large bronze figures that strike the hours on a bell, the copper statues of the Virgin and Child, and the clock face are all original. The clock displays not only the time of day but also the current zodiac sign and phase of the moon.
A visit to the clock tower is generally included in tours of the highlights of St. Mark’s Square (Piazza San Marco), including St. Mark’s Basilica, Doge’s Palace (Palazzo Ducale), and the bell tower; skip-the-line tickets are a must for these popular sights. Tours include an explanation of the internal clock mechanism and a climb to the top of the tower.
