Known as ?Olympic Spectaculars?, the rings were often unveiled to coincide with key milestones in the run-up to 2012 or the arrival of the Olympic Torch to that area. Locations include Heathrow Airport, the entrance to the Channel Tunnel, George Square in Glasgow, outside the city halls of Cardiff and Belfast, and the Mound in Edinburgh, while the Newcastle and Gateshead Rings can be seen hanging on the famous Tyne Bridge.
In London Olympic Rings were lowered from Tower Bridge to mark 30 days to go, and at Kew Gardens the giant rings were formed using flowers ready for the arrival of the Olympic Torch Relay on day 67 of its journey.
The largest official Olympic Spectacular can be seen in south London at Richmond Park National Nature Reserve, where they have been mown into the grass by the Royal Parks? shire horses and are visible on the Heathrow flight path.
The five Olympic rings represent the five continents and the meeting of athletes from throughout the world at the Olympic Games; they are one of the most recognisable logos in the world.
Seb Coe, LOCOG Chair, said earlier this month: ?The Olympic Rings are an iconic symbol, inspiring athletes and uniting people around the world. To athletes they represent the culmination of thousands of hours of training and reaching the highest level in sport. These Rings will excite and inspire visitors coming to London.?
