Catania located at the foot of Mount Etna has many things to see and do, the majestic Cathedral of Saint Agatha patron saint of the city, it was built in 1078 on the ruins of the Roman baths Achilliane still visible by the initiative of Count Ruggiero, but the building you see now is Sicilian Baroque and dates back to 1711 as it was completely rebuilt after the earthquake of 1693, not many people know that the bell tower houses the 3rd largest bell in Italy after St. Peter's in Rome and the Duomo of Milano, in the center of the piazza dominates the symbol of the city "u Liotru", or the Fontana dell'Elefante, assembled in 1736 by Giovanni Battista Vaccarini. It portrays an ancient lavic stone elephant and is topped by an Egyptian obelisk from Syene. Legend has it that Vaccarini's original elephant was neuter, which the men of Catania took as an insult to their virility. To appease them, Vaccarini appropriately appended elephantine testicles to the original statue, then adjacent to the Cathedral there is the historic building that houses the Diocesian Museum.
