The Bell Towers of Venice

The skyline of Venice once bristled with bell towers (campanili), as we can see in an engraving from the second half of the 18th century.

There were more than a hundred such towers, of which only sixty-six remain standing. In addition to the obvious problem of subsidence, earthquakes, hurricanes, lightning and fires have also taken their toll (no pun intended). 
Campanile di San Marco, Piazza San Marco, Venice
The tallest bell tower, by a margin of almost one hundred feet, is that of the Basilica San Marco. Soaring to a height of 318 feet, it is nicknamed el paron de casa (the master of the household). The shortest is that of Sant'Eufemia. San Samuele boasts one of the oldest bell towers, while Sant'Elena has the youngest, dating back little more than half a century.  
The bell tower, or campanile, Santa Margarita, Venice
The remains of towers which have been destroyed can be seen all over the city. Sometimes, as in the case of Santa Margarita, what is left is very visible, in other cases it is less so.

The doors to several bell towers sport a scacciadiavoli, a grotesque head intended to ward off evil spirits. The most famous can be found at Santa Maria Formosa, but scacciadiavoli can also be seen at other bell towers, such as those of San Trovaso and San Bartolomeo. 
Leaning bell tower, or campanile pendente, San Giorgio dei Greci, Venice
The city of Pisa might be famous the world over for its leaning tower, or torre pendente, but here in Venice we have not one but two, namely those of Santo Stefano and San Giorgio dei Greci.
