The clock tower, located close to theBasilica, was built at the end of the 15th century and the central part wasdesigned by M. Codussi. On the terrace at the top of the Tower, two dark bronzefigures, the Moors strike the hour against a large bell. Of notableinterest are the complex clockwork mechanism and the great gold and blue enamelclock-face that indicates the hour, the phases of the moon and the motion ofthe sun.
