We have become so familiar with modern day facilities that we often tend to overlook the mastery behind some seemingly common amenities. Elevators, man made cages whose history does not stretch too long over 150 years, that take passengers up and down buildings more or less tall, have changed our lives completely. Elisha Otis is credited for developing the modern elevator, but we've come a long way since then. Buildings become taller, and the demand for faster transportation in between floors continues to grow.

It only take a push of a button, so it's easy to think elevators are up to date and no longer deserve some special attention. However, I bet I can change your opinion if you follow me on this tour of the world's fastest, most amazing, and most luxurious elevators. Imagine 45 10-story buildings one on top of the other and an elevator in the middle that is able to reach the very top. This is no longer a fantasy concept. You will see how it is not the fastest elevators that are the most expensive, but the ones that took technology and comfort to a whole new level, transforming an elevator ride into a pleasant journey you won't forget. Some of the prices associated with the elevators have been adjusted for inflation.
