A Sailortown is a district in seaports that catered to transient seafarers. These districts frequently contained boarding houses, public houses, brothels, tattoo parlours, print shops, shops selling nautical equipment, and religious institutions offering aid to seamen; usually there was also a police station, a magistrate's court and a shipping office. Because it took several days, in the past, to unload ships, crews would spend this time in sailortown. These were "generic locations—international everyplaces existing in nearly every port." Cecily Fox Smith wrote that 'dockland, strictly speaking, is of no country—or rather it is of all countries'". Sailortowns were places where local people, immigrants, social and religious reformers, and transitory sailors met.

Tiger Bay was the local name for an area of Cardiff which covered Butetown and Cardiff Docks. Following the building of the Cardiff Barrage, which dams the tidal rivers, Ely and Taff, to create a body of water, it is referred to as Cardiff Bay. Tiger Bay is Wales’ oldest multi-ethnic community, with sailors and workers from over 50 countries settling there from the mid-19th century onwards.
