Bucentaur
The bucentaur ( bew-SEN-tor; bucintoro in Italian and Venetian) was the ceremonial barge of the doges of Venice. It was used every year on Ascension Day (Festa della Sensa) up to 1798 to take the doge out to the Adriatic Sea to perform the "Marriage of the Sea" – a ceremony that symbolically wedded Venice to the sea.
