DUBLIN is truly a city of two names, Dubh Linn and Áth Cliath, each reflecting a distinct part of its ancient past. The English name ‘Dublin’ derives from the Gaelic ‘Dubh Linn,’ meaning ‘Black Pool,’ itself adapted from the Viking Dyflin. The name refers to the dark tidal pool where the River Poddle met the River Liffey, a spot that now forms part of the gardens of Dublin Castle.
