Butetown and Tiger Bay seafarers took a heavy toll from U-boat attacks in WW1.
The boarding houses of Butetown and Tiger Bay have long provided lodgings for seafarers when ashore and the many local public houses would have been well frequented by them too.
319 overseas seafarers were shown as having lodgings in the many boarding houses in the Butetown and Tiger Bay areas. More than two-thirds of these were employed in the engine room. We have plotted their addresses on the map in red. The blue dots indicate the public houses.
