A GIANT set of Olympic rings has been unveiled on the entrance to the Channel Tunnel in France.
The 9.4m wide and 4.6m high blue, yellow, black, green and red rings were transported in segments to the entrance in Coquelles, near Calais.
They will be hard to miss for the thousands of sports fans who travel to the Games from Europe on Eurostar trains to St Pancras International.
Five rock climbers spent two nights installing the rings.
