While the Eiffel Tower (built between 1887 and 1889) was and is originally just a phenomenal cultural building, there is a ongoing project to use this magnificent structure as part in experimental space travel program.
An secret french space technology enterprise, aided by chosen NASA and ESA specialists, has noticed that the Eiffel Tower could be used as part of highly advanced space travel apparatus. The plan is to use the tower as an basic structure - a skeleton if you will - and later adding the technology wich could be humorously called as "meat and organs around the bones".
Project Eiffel Cannon is not an traditional rocket propelled space travel program. Instead, it uses state-of-the-art worm hole technology to "shoot" the crew and their equipment to any planet or moon that can be detected visually. In time of action, several truckloads of technology would be transferred to the Eiffel Tower. Also a "aimer" component would be needed for the tip of the tower, since the tower is fixed and cannot be turned.
This technology allows complex buildings to be inserted with it's crew and life support to the other side of the galaxy at an instant. The only requirement is that the structure being transferred fits under the Eiffel Tower.
This technology haven't been used yet due the high risk of uncontrolled wormhole leading to possible massive disaster. It is planned that this wormhole technology is being tested at moon, but sofar the project needs bigger funding.
