 Nearby was the "Traghetto Del Buso" (Crossing Of The Hole), where prostitutes' clients crossed the Grand Canal to enter the red-light district.Casanova was said to be a frequent visitor.This situation continued until the 18th century when, to encourage tourism, younger prostitutes were allowed to work throughout in the city and older and less attractive prostitutes were restricted to the nearby "Rio terà delle Carampane".
