The oldest tower clock in the world is located in the small town of Chioggia in the south of the Venetian Lagoon in Italy. It was installed in 1386 on the tower of Santa Andrea. In fact there is another clock built in the same year in Salisbury , but some indications give the precedence to the one in Chioggia.
A curiosity about the clock is that it is divided into 24 hours, numbered twice from I to XII and has only one pointer. In this way the it turns only one time a day.
Inside the tower there is a small museum where you can see the mechanisms that since the Middle Ages command this magnificent clock.
