Eighteen months after the end of London 2012, the wings are gone and the ugly duckling has finally turned into a swan. The Aquatics Centre boasts two 50-metre swimming pools, a diving pool, dry diving room and a gym.
The swimming complex was commissioned in 2004 when London was still considered an outsider in the race to host the 2012 Olympics.
The most expensive leisure centre ever built in Britain will be unveiled today four days before it opens to the public.
The £250m London Aquatics Centre was meant to be the iconic venue of the 2012 Olympic Games. But the sweeping curves of the 3,000 tonne roof were hidden by two temporary "wings" containing 15,000 spectator seats.
London is leading the way when it comes to rising house prices in Britain. 22 of the 33 London boroughs have set new records for the average house price last November. The biggest increases were in the boroughs of Enfield Greenwich and Hounslow
British Diving will move into the Aquatics Centre on the Olympic Park in Stratford next Spring.
National Performance Director Alexei Evangulov said: "We are really pleased to have an HPC [High Performance Centre] at the pool that was used for the Olympic Games and are excited about when the doors open.
"The London Aquatics Centre is a fantastic facility with world class boards and dry land provision. A facility like this will help shape the next generation of athletes and allow them to see what an elite competition venue is like on a day-to-day basis.
"The pool holds great memories for not only the British public but also our divers and all athletes that use this centre will have a small taste of the Olympics every time they walk through the door."
The successful staging of the London 2012 Olympics has led to other countries turning to Britain to help deliver their own events, according to a government official.
Reacting to news that the UK had met its four-year target of raising £11 billion worth of economic benefit from the Games in 12 months, Trade and Investment Minister Lord Green said:
"The delivery of London 2012 on time and on budget led to hosting nations turning to the UK to help deliver their own events with supply opportunities running into the billions.
"UK Trade & Investment has played a key role in helping British companies maximise these opportunities and the result is a £11.06 billion boost to the UK economy from the Games, reaching our four-year target in just over a year."
A four-year target of raising £11 billion worth of economic benefit from the London Olympics has been met in 12 months, the Government has announced.
The country has benefited from new foreign investment, additional sales and firms winning contracts since last summer's events, according to a report.
The total includes £130 million of contracts won by UK companies for next year's soccer World Cup in Brazil, and the next Olympic Games, in Rio in 2016.
Daniel Radcliffe looks set to play London 2012 boss Lord Coe in a film about his track battles with fellow athlete Steve Ovett three decades ago. The Harry Potter actor will star in 'Gold', which looks at the tense rivalry between the middle distance runners.
The competition between Ovett and Sebastian Coe is seen as one of the greatest sporting rivalries as they dominated middle distance running, setting world records and amassing medals.
All this week we're looking at the legacy of the London Olympics one year on, and asking whether its main aims are being achieved.
One of its commitments was to inspire more people to volunteer.
A recent survey found that almost half of Londoners were inspired by the Games to volunteer for the first time, or more often.
Simon Harris has been to meet one of last year's gamesmakers, to find out if he's still giving up his time to help others.
One year on from the London Olympics, a new photography exhibition looks at the Games impact on some of the 70 thousand volunteers.
The free display, at Stratfords 'ViewTube' tells a visual story about 17 gamesmakers who made the whole thing possible.
"There was a suggestion that there was a credible attack on the electricity infrastructure supporting the Games.
The clock was absolutely ticking.
We effectively switched to manual, or had the facility to switch to manual.
It's a very crude way of describing it, but effectively we had lots of technicians stationed at various points."
