With less than 50 days to go before the Paris Summer Games, a display of the Olympic rings has been unveiled on a symbol of the French capital -- the Eiffel Tower.

The five rings were installed 70 meters from ground level overnight on Friday without prior notice.

They are made from recycled metal and measure 29 meters long and 13 meters wide.

A Japanese woman, in Paris on her honeymoon, took photos of the tower and Olympic symbol. She said she is excited that the Games will open soon.

The president of the Paris Games organizing committee, Tony Estanguet, said there will be many surprises up until the end of the event.

He said the committee is trying to be as creative and bold as possible, adding it will not disappoint people and the opening ceremony will be particularly special.
