It is necessary to very accurately conduct geological and topographic surveys, because heavy loads will be distributed over a large area, and the soil may have different properties and different mobility.
This makes a lot of sense when constructing massive staircases that are the architectural landmark themselves. We definitely don't want unexpected accidents to happen due to poor design standards, wrong planning, and inappropriate technical processes.
Aside from being a beautiful attraction with its turtle-paced speed, I also find that funicular beside the staircase to be a different kind of human experience!
Thank you very much! As a rule, the buildings of those times were designed and built very conscientiously, as they say: for centuries.
I could not check how this funicular functions, I was in a hurry and decided to test my strength by going up the stairs on foot).
