A dark sheltered pool used to occupy this area, and it is from this pool that Dublin takes its name... Dubh Linn meaning 'black pool'. Within the grounds are dotted modern sculptures including a glass snake, 2003 Special Olympics memorial and a bust of murdered investigative journalist Veronica Guerin (played by Cate Blanchett in the eponymous film). Laze on the wooden benches or follow the central lawn's path as it traces out a large Celtic design. And look out for visiting dignitaries who use this space as a rather fetching helipad. Beats a capital 'H'.
