What time and effort does it take to create a cathedral?

Explanation:

One of the obvious things that we can appreciate about Medieval architecture is the enormous amount of effort the people put into their constructions, as well as the time it took for them to build some of their most impressive monuments. There are many aspects of Medieval culture that we can appreciate based on this fact.

We can also conclude that their technology was less developed than ours, as it took a very long time for them to finish a project.
