Whole sections of the park are being rebuilt with new cafes, community centres and gardens added, as part of a 18-month scheme.
The Riverside Hockey Arena has been dismantled, the largest McDonald's in the world has gone and the temporary seating stands on the Aquatics Centre are being taken down.
The competitors' accommodation is being transformed into almost 3000 luxurious flats, new homes and schools are under construction and the whole area will be surrounded by a new park.
The Queen Elizabeth Olympic Park reopens in part in July and will re-open fully from 2014. Planners hope that within 20 years, the new district will be home to 8000 people.
It will still host sporting events, however, from football to athletics.
The London Anniversary Games will be held at the Olympic Stadium in July, including the Diamond League athletics meeting expected to attract stars including Jamaican sprinter Usain Bolt.
English Premier League club West Ham United will then become the main tenants of the venue, which hosted the athletics and the opening and closing ceremonies.
The 80,000 capacity stadium will be converted to a 54,000-seater venue in time for the 2016-2017 football season.
