Radisson Blu St. Helen's Hotel, Dublin


Visitors can catch all sorts of Dublin events at 3Arena, previously the O2 Arena. It has a capacity of 13,000, making it the largest indoor arena in Ireland. Choose from comedy, variety shows and concerts from world-renowned bands and performers.

Located just down the coast, the Radisson Blu St Helen's Hotel in Dublin is perfectly situated for those visiting the 3Arena.   

A music arena with a difference

The arena features a state-of-the-art design. The furthest seat is only 60 metres from the stage, which is impressive for such a large venue. This is due to the “fan-like” arrangement of seats, which architects have likened to Rome’s Colosseum. The design of the building also makes for world-class acoustics.
