The final steel ring was connected to the £22.7m ArcelorMittal Orbit in October, making it 114.5m (376ft) tall. Visitors will be able to go up the 35-storey structure in a lift, to take in panoramic views of London, and will have the option of walking down its spiral staircase.
In the north of the Olympic Park is the Velodrome which is the most sustainable venue on the site, in terms of design and construction. Olympic cyclist Chris Hoy and Team GB were consulted during the design process to ensure the best conditions for athletes inside the building.
The temporary Riverbank Arena will be used for Olympic Hockey and Paralympic 5-a-side and 7-a-side Football. To reflect the colours of the Games, the playing field is London Blue in colour - to contrast with the yellow ball – and the pitch surrounds are coloured London Pink.
Wheelchair Tennis will be played out at Eton Manor during the Paralympic Games. During the Olympic Games participants in Aquatics events will be able to make use of temporary training pools at the complex, including three 50m pools for swimmers and smaller pools for synchronised swimmers and Water Polo players.
The Olympic Stadium will have a capacity of 80,000 during the Games, comprising 25,000 permanent seats in its permanent lower tier and a temporary lightweight steel and concrete upper tier holding a further 55,000 spectators that can be removed after the Games.
The Olympic Parklands contain 4,000 semi-mature trees, more than 300,000 wetland plants and more than 10 football fields-worth of nectar-rich annual and perennial meadows designed and sown to flower during the 2012 Games.
About 2.5sq km of former contaminated, industrial land has been transformed into what is now the Olympic Park. Once the Games are over it will be called the Queen Elizabeth Olympic Park. All pictures copyright Jason Hawkes
