3Arena Dublin

Dublin's largest indoor arena in the Docklands, hosting major international concerts and shows.

The 3Arena is Dublin's largest indoor concert venue, sitting right on North Wall Quay in the lively Docklands district. With a capacity of around 13,000, it consistently ranks among Europe's busiest arenas by ticket sales. Originally a warehouse building, it was converted into "The O2" arena in 2008 and rebranded 3Arena in 2014 after Three Ireland's takeover. The venue hosts world-class acts in pop, rock, comedy and musical theatre, and its waterfront location makes it easily accessible from central Dublin.
