3Arena
The 3Arena is a 14,500-capacity amphitheatre located at North Wall Quay in the Dublin Docklands in Dublin, Ireland, which opened on 16 December 2008. It was built on the site of the former Point Theatre, a smaller music venue which operated from 1988–2007, retaining only some of the outer facade. The Point Theatre was branded as "The Point Depot", in recognition of its original role as a railway goods handling station.
From 2008 to 2014, the 3Arena was known as The O2. Its 14,500 capacity makes it the largest indoor arena in Ireland. The venue was rebranded on 4 September 2014 as the 3Arena due to the takeover of O2 Ireland by Three Ireland.
The venue is owned by Live Nation. In 2011, the venue was named as the fifth busiest arena in the world with ticket sales of 670,000 putting it behind The O2 in London, the Manchester Arena, Antwerp's Sportpaleis and Melbourne's Rod Laver Arena.
Naming
Following its closure in 2007, the site underwent major redevelopment and was renamed The O2 after the telecommunication brand, O2, similar to The O2 in London. In 2008 O2 paid €25 million for the naming rights for 10 years. Following the sale of mobile network operator O2 Ireland to rival 3 Ireland in June 2014, the venue was renamed as the 3Arena on 4 September 2014.
