The Olympic rings can now be seen by visitors flying into London for the games after the giant symbol was mown into grass by shire horses.
The logo, which can be seen at Richmond Park, is 300 metres wide and 135 metres tall, and is visible from the Heathrow flight path.
Six shire horses, which have been used for centuries in the park, performed the task and will maintain the logo throughout the Olympics.
– Lord Coe, London 2012 Chairman
The rings represent the culmination of thousands of hours of training and reaching the highest level in sport. They will excite and inspire visitors coming to London."
Richmond Park is one of several landmarks across the UK bearing the symbol, including Tower Bridge and St Pancras Station.
The park will also serve as part of the route for road race cycling at the games.
