If it's an RPG, it should follow the classic naming convention. Jungles & Journeymen, Ships & Swashbucklers, Prisons & Pirates.
Note that it absolutely must be [P]lacesofsomekind & [P]eopleofsomekind, not just some random two words jumbled together. This is the way.
Brothels & Buccaneers?
One of the AD&D 2nd edition historical reference campaign sourcebooks covered the period 1550-1650, but it was named A Mighty Fortress, which isn't at all appropriate for a swashbuckling game.
There are a few tabletop RPGs with a similar setting: 7th Sea, Savage Worlds of Solomon Kane, Witch Hunter: the Invisible World, LexOccultum, Flashing Blades, Pirates of the Spanish Main, Buccaneer: Through Hell & High Water, 50 Fathoms, Zweihander, Burning Wheel, Lamentations of the Flame Princess, Hexxen 1773, Swashbuckling Adventures, Swashbucklers of the 7 Skies, Honor & Intrigue, All for One: Regime Diabolique, GURPS: Swashbucklers
