Every year, the first Sunday of September, the Historical Regatta comes back in Venice, the most traditional among the venetian events, which took place for the first time the 10th of January 1315 . The sumptuous event, organized in the Serenissima times to celebrate the military victories or to honour the foreign dignitaries, today is made up of two different parts: the historical parade and the rowing boat races. The Historical Regatta starts out with the colourful procession on the Grand Canal, formed by the Bissone, the Bucintoro and the boats of the venetian rowing clubs; the event commemorates the Queen of Cyprus, Caterina Cornaro, coming to Venice, which marked the beginning of the Venice rule over the Mediterranean islands. Venice and its lagoons is a Unesco World Heritage site.
