This tower allows us to have a fabulous view of the city of Paris and is an alternative to the typical climb of the Eiffel Tower, though I would recommended going up at least once. But if you've been up, you can go up the towering skyscrapers for a different experience. For € 10 go up in Europe's fastest elevator, go up 56 floors in 38 seconds, without stopping, James Bond style. There awaits a plant conservatory where you will see Paris by 360 ° and at a height of 195m, there is also a cafe and souvenir shop. Once there you can climb to the roof walk, reaching 210m in height. The views are amazing, and you can see the Eiffel Tower and walk from one to the other in about three quarters of an hour, and thus take advantage of the walk to visit another area of the city .
