Brothels acted as the homes and workplaces of the courtesans. During the 16th century, brothels could be found in Florence, Venice, Rome, and Monteriggioni, and all of them appeared to have small rooftop gardens, which distinguished them from other nearby buildings. In Rome, other than its central brothel, the Rosa in Fiore, there were several small faction buildings that could be renovated into brothels, allowing the courtesans that resided nearby to be hired.
In 18th century, brothels prospered in the New World as well as they had in the Old World: in Port-au-Prince, La Dame en Rose served as a meeting place. Edward Kenway had one built in the small port town at the Great Inagua to provide a home for dancers who entertained his crew.
