elevators and skyscrapers
Throughout the history of architecture, there has been a continual quest for height. Thousands of workers toiled on the pyramids of ancient Egypt, the cathedrals of Europe and countless other towers, all striving to create something awe-inspiring. People build skyscrapers primarily because they are convenient -- you can create a lot of real estate out of a relatively small ground area. The driving force behind skyscrapers is building materials, primarily concrete and steel. This and the engineering of these structures, which had to develop with their conception, is what made them possible.
