Campanile di San Marco - Venice Italy

The campanile of St. Mark’s is an imposing square plan tower about 99 metres high, crowned by a spire that was once a lighthouse for shipping. It is the prototype of all the campaniles of the lagoon area. It was first built in the 12th century on the site of what was probably a watchtower and rebuilt in its current form early in the 16th centurywith the addition of a belfry and with the spire faced in copper and topped by a sort of rotating platform with a statue of the Archangel Gabriel which functioned as a weathercock
