In the first two days of the four-day event, over 100,000 tourist presences were registered in the lagoon city including 55,000 on Sunday alone.
More than 18,000 more visitors thronged to the city from other towns in the Veneto region on Sunday.
There were around 25,000 foreign visitors, most of whom spent the night in Venice.
The biggest contingent were the French (23.58%), followed by the British (12.97%), Spanish (12.89%), and Germans (7.24%).
The theme of this year's Carnival is "Remember the Future", and the extravaganza kicked off with a son-et-lumiere show on the Grand Canal called "Venezia lux futura".
The event will reach its climax on Tuesday, Mardi Gras. (ANSA).
