The Eiffel Tower is the symbol of Paris and France. And with around 7 million visitors per year, it is arguably the most visited building in the world. The Eiffel Tower company unveiled its plans to add some new features to the landmark structure. Some of these modifications include the installation of giant viewing bays and the introduction of glass floors on the walkways on the inside edge of the open spaces between the pillars. These upgrades are welcome changes, as almost half the visitors stop at the first stage and don\'t really climb all the way up to the more important parts of the tower. Some 25 million euros will be spent to offer the tower visitors a strong first impression on the first stage. The work will begin next year and last for about 17 months.
