That some things in history took the span of multiple generations to finish was quite the revelation to me. The Cologne Cathedral took over 600 years to finish. As another example, this amusing video [1] tells the story of how King Louis XIV wanted a map of the entirety of his kingdom from Cassini, and how it was apparently Cassini's great grandson (4 generations over 120 years) who finally concluded the project.
For some generations in the middle of such projects, I can imagine that their huge undertaking is just "something they do", essentially just their job, and from their point of view it has always been there, and will always be there to the extent of their lifetime.

Do we still have anything like this?
