The bell tower of Saint Mark’s is one of the city symbols called affectionately El Paron de Casa (The landlord). It is separated from the basilica, has a square plan of 12 meters and is 98.6 meters high. The entrance to the bell tower is through the Loggia of Sansovino. It was originally built in the ninth century as a watchtower and as a beacon but has undergone numerous modifications. In 1609, Galileo used it to make a demonstration of his telescope. The current tower was rebuilt in 1915. Up to 1800 in the shadow of the bell tower were taverns and wooden shops and from these comes the joke about a Venetian 'andemo a bever un’ombra' (let's go have a glass of wine in the shade). At the time of the Serenissima, some crimes committed by the clergy were punished by the exposure of the offender in a cage hanging from the bell tower. Every year, during Carnival, from the bell tower you can witness the flight of the angel, as well as at the times of the Serenissima you can see an "angel" in the flesh who ‘flies’ to the Palazzo Ducale.
