The O2 is named after its primary sponsor, the telecommunications company O2, a subsidiary of Spain’s Telefónica
What was the O2 called before?
The O2 was originally called the Millennium Dome
Back in 2000, this massive white dome opened as London’s centerpiece for millennium celebrations. Designed by the Richard Rogers Partnership, it housed the Millennium Experience—a government-backed exhibition packed with art, culture, and tech showcases. Once the exhibition wrapped up, the dome sat mostly empty until developers saw its potential.
What was the O2 built for?
The O2 was originally built to house the Millennium Experience
This wasn’t just any exhibition—it was a massive, taxpayer-funded showcase celebrating the turn of the century. Think interactive displays, cutting-edge art installations, and exhibits highlighting British innovation. The dome’s genius design? A vast, column-free interior that could handle millions of visitors during its year-long run. When the celebration ended, the future of the dome looked shaky—until someone had a better idea.
When did the Millennium Dome become the O2?
The Millennium Dome was renamed The O2 on 31 May 2005
That’s when O2 plc, the telecom giant, inked a £6 million-per-year naming rights deal. Suddenly, this iconic structure wasn’t just a relic of the past—it was reborn as a premier entertainment and leisure venue. The rebranding kicked off a fresh chapter, turning the dome into a go-to spot for concerts, sports, and major events. It was all part of a bigger push to revive the Greenwich Peninsula.
What is inside the O2?
The O2 complex includes a multi-screen Cineworld, Oxygen Freejumping trampoline park, 12-lane Hollywood Bowl, premium shopping at ICON Outlet, bars, restaurants, and event spaces
This place is a full-blown entertainment district. You’ve got a massive arena seating up to 20,000, making it one of the busiest venues on the planet. Beyond that, there’s a cinema, trampoline parks, bowling alleys, and enough dining options to keep you busy for hours. And let’s not forget the public art and green spaces sprinkled throughout. Honestly, it’s one of those rare spots where you could spend an entire day and still not see everything.
Is EE part of O2?
No, EE and O2 are separate companies
EE popped up in 2012 when Orange and T-Mobile merged, while O2 started life as BT Cellnet before going solo in 2002. Both are big players in the UK mobile market, going head-to-head with Three and Vodafone. They’re competitors, not siblings under the same corporate roof.
Is O2 owned by BT?
No, O2 is not owned by BT
As of 2026, O2 UK is co-owned by Liberty Global and Telefónica, operating under the Virgin Media O2 banner. BT used to call the shots back when it was still BT Cellnet, but it sold off its stake way back in 2002. Corporate ownership can shift faster than you’d think, so it’s always worth double-checking the latest details.
Did Wizkid sell out the O2 arena?
Yes, Wizkid sold out all three of his O2 Arena shows in 35 minutes
His first show on 28 November sold out in just 12 minutes—yes, you read that right. The remaining two dates followed suit shortly after. With a capacity of 20,000, the O2 Arena is a hot ticket for international artists. Wizkid’s Made in Lagos Tour absolutely dominated the venue’s 2026 calendar.
What is the millennium known as now?
The Millennium Dome is now known as The O2
This landmark sits on the Greenwich Peninsula, standing as London’s go-to spot for culture and entertainment. From music concerts to high-profile sporting events, it’s become a symbol of the city’s ever-evolving landscape. Its transformation proves that even the most unlikely structures can find a second life.
Who has sold out the O2 Arena?
Numerous artists have sold out the O2 Arena, including Wizkid, Ed Sheeran, Taylor Swift, and Adele
The O2 Arena isn’t just another venue—it’s a bucket-list destination for performers. Its size, sound quality, and reputation for unforgettable shows make it a top-tier choice. Many artists book multiple nights to meet demand. If you’re an act looking to make a statement, selling out here is a badge of honor.
How did they do the lights above the Millennium Dome?
Diode lasers are used to produce the beams that sweep over the capital
These lasers bounce off two mirrors and shoot through a hole in the old observatory building. The result? The famous "London Eye Beam," a dazzling light show visible across the city. At night, it’s one of London’s most iconic skyline features—proof that even functional structures can become works of art.
What restaurants are at The O2?
The O2 hosts a diverse range of restaurants, including Hook (fish and chips), Beer + Burger Store, by CHLOE., Busaba Eathai, Gaucho, Scarlet Rasoi, Rodizio Rico, and Thunderbird Fried Chicken
Whether you’re craving casual eats or something a little fancier, The O2’s got you covered. From British classics like fish and chips to global flavors like Indian and Brazilian, the options are endless. And if you’re not in the mood for the dome itself, the ICON Outlet nearby has even more dining choices.
How long does up at the O2 take?
Up at The O2 takes 90 minutes to complete
This isn’t your average walk in the park—it’s a guided climb along a 380-meter fabric walkway suspended 52 meters above the ground. You’ll be clipped into a harness the whole time, so no need to worry about heights. The payoff? Breathtaking panoramic views of London. Pro tip: book ahead, because this experience is wildly popular.
