"Despite its origins as a railway goods handling station for the adjacent Dublin Port, Ireland’s largest indoor arena is a decidedly modern venue, with a capacity of 23,000; it was transformed into its current role in 1988 before being completely redesigned in 2008. This is the city's only arena-sized venue, so it's where you'll go to take in big-budget acts like One Direction, and large-scale performances à la Cirque du Soleil. Our advice when it comes to seating? Pick up seats in the central column of the first row, unless you're into that whole mosh pit thing—and if you are, be aware that it's restricted to those over the age of 14." - Fionn Davenport
