London will welcome the athletes and visitors in a king size way with a 300-meter wide logo etched into the grass for the duration of the Olympic Games. 

The rings have been made on the London's Richmond Park with the help of six of The Royal Park's shire horses. The grass will be regularly trimmed throughout the summer to keep the logo fresh. 

Richmond Park has been chosen as the site of logo because it lies under the flight path of Heathrow Airport as athletes and the visitors make their descent into London. 

The circles will be maintained by two horses, Jim and Murdoch, who will cut the road side verges regularly in Richmond Park and have been used to maintain the park for many years.

"Jim and Murdoch can maneuver the mower around tight corners, and regularly cut the grass here at Richmond Park," Adam Curtis, Assistant Park Manager of Richmond Park for The Royal Parks told reporters. "They are our secret weapon because they maintain the Park without damaging the unique grassland and wildlife."

"The Olympic Rings are an iconic symbol, inspiring athletes and uniting people around the world," London 2012 Organising Committee chair Sebastian Coe told reporters. "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."

Giant-size Olympic rings have been made at major tourist attraction all over London and continues to increase the charm and excitement of the upcoming event.
