Bulldozers have begun tearing down buildings to make way for the 2012 Olympic Park in east London.
The Olympics Park covers 500 acres
The Olympic Delivery Authority (ODA) took control of the land from the London Development Agency on Thursday.
In three years 208 businesses, 425 residents, 35 traveller families, and 64 allotment holders have relocated.
The 500-acre site will include a main stadium, aquatics centre, velodrome, three sports arenas, a hockey centre and accommodation for competitors.
Situated near to the proposed Olympic transport hub in Stratford, the Park will allow easy access to the O2, in Greenwich, and the ExCel centre in Docklands, where other events will be held.
