To celebrate 90 years of Citroën and 120 years of the Eiffel Tower, the two are joining forces again, after 75 years, in a stunning display of Créative Technologie.

Every night for three months from last Thursday, a special 12-minute light show will take place on the Eiffel Tower - one minute for each decade the 'Iron Lady' has stood proudly in the heart of Paris.

Last Thursday evening, Citroën streamed live footage of the event from webcams mounted in 10 new Citroën C3's positioned at key vantage points around the tower.

The footage was broadcast at www.toureiffel.citroen.com. As well as taking advantage of the new C3's 'Zenith' windscreen, the webcam pictures were displayed in vertical 9:16 format, a revolution for internet video.

Citroën and the Eiffel Tower enjoyed a historic partnership for almost 10 years between 1925 and 1934, when André Citroën had the company's name displayed in lights on the iconic structure. A total of 250,000 light bulbs and 600 kilometres of electric flex were used to make the 30-metre high letters. The spectacle was recorded in the Guinness Book of Records as the world's largest advertising sign. The illuminations were so bright that Charles Lindbergh used the tower as beacon when coming into land after his solo flight across the Atlantic.
