The Eiffel Tower in paris

Even if 6 million visitors climb the Tower each year, the number of those who have set eyes on the Tower but never foot coupled with those who know of the Tower but have never even caught a glimpse of the monument are far more numerous.
Its simplified representation is but an inanimate object, an unchanging reference point. Yet, differing from many other structures built in the past, it is alive, ever changing and evolving.

The most spectacular transformations are also those that are the most visible: it has changed color six times in its lifetime and its lighting effects have been designed at different moments to decorate the tower for a day or for longer periods of time. Following many different lighting styles, the present day system has been highlighting the internal structure of the Tower for more than ten years now.

Less spectacular yet visible are the developments that have been added to the different levels such as the various pavilions and constructions on the first and second floors. Also the roofing of the galleries and shelters providing refuge from bad weather conditions including the landing stages, covered walkways, etc., as well as the numerous technical and service quarters and the spaces located directly over or under these levels.
