In previous centuries this holiday held an important role in the social and political life of Venice, which resulted in one of the most important and sumptuous celebrations, interweaving the legend, myth and history of the city. If, historically speaking, the Sensa is the result of an overlapping of civil and religious rites and events through the ages, today we prefer to give it the meaning of festivity of the Sea and therefore of a festivity of a city which draws its raison d'être from its relationship with the sea. The roots of the Sensa Feast-day lie in the history of Venice, and more specifically in the episode when Doge Ziani acted as mediator between Pope Alexander III and Emperor Frederick Barbarossa. The Doge of the Serenissima used this rite to demonstrate the Republic’s dominion in the gulf. The doge and his entourage embarked on the Bucintoro. On reaching the mouth of San Nicolò port, the Doge threw a gold ring into the sea. The famous Sensa fair attracted visitors from all over Europe. It took place in Saint Mark’s Square and lasted 15 days. It gave merchants an opportunity to display rare merchandise, new fashions, art and produce from all over the world. Today the ceremony is not as magnificent as in previous centuries, but the symbolism of the mystic marriage to the sea is still evident and is certainly still valid today. The Mayor of Venice, civic dignitaries and religious and military representatives leave Saint Mark’s Square and sail to the Port of S. Nicolò where the ritual ring throwing takes place.
