Dublin City Zoo
The spelling of Dublin was originally "Dubh Linn," which means "Black Pool" in Gaelic, referring to an ancient treacle lake in the city. The lake is now part of the penguin enclosure at the Dublin City Zoo.
The Shelbourne, now a newly renovated and upscale hotel in Dublin, was where the first Irish Constitution was drafted and signed in 1922. The hotel overlooks St. Stephen’s Green, Europe's largest garden square.
