'Dalkey' comes from the Irish 'Deilginis,' meaning 'thorn island,' referring to Dalkey Island's thorny landscape offshore—a nod to its Viking-era history as a bustling slave-trading port with safer harbors than Dublin. This etymology evokes the area's rugged coastal roots, from ancient pilgrimage sites to Norman castles, shaping its enduring seafaring character.
