Just outside the walls of Dublin Castle, the Dubhlinn Garden occupies the site of the ‘black pool’ on the River Poddle that gave Dublin its name in Viking times. The Irish name of the city, Baile Átha Cliath, comes from the older Gaelic settlement at the ‘ford of hurdles’ that crossed the Liffey nearby.

The colours of the walls are reminiscent of the logo for the Dublin Millennium in 1988, the year of Anna Livia, milkbottles and fifty-pence pieces.
