For over a thousand years the city of Venice has been the capital of the Venetian Republic and was called “Serenissima”, the Dominant, and the Queen of the Adriatic. With its characteristic urban planning and artistic heritage, Venice is universally considered one of the most beautiful cities in the world and is included, together with its lagoon, among the UNESCO World Heritage sites in Italy. The city of Venice is affected by subsidence mainly due to natural and anthropogenic causes, and to the eustatism linked with global climatic changes: from the beginning of the last century to the ’70s, the sea water level rose by 9 cm in Venice. Venice has always been intimately linked with the water surrounding it. In the ancient and mystical annual Marriage of the Sea ceremony, established in AD 1000, the Doge (elected ruler of the Republic) threw a consecrated ring into the murky waters and declared the city and sea to be an indissoluble oneness.
