You can't understand the scale of it until you experience it in person. The way I thought of it was that it is a cathedral made for giants.
It's also a symbol of all the money and gold, the real values and the secrets of the church...
If God exists, you think he would want you to sacrifice and spend it all on gold and salaries of locals ?
Exactly. And it was a great marketing tool for catholicism, imagine simpler (even if rich) folks came to visit the pope and experienced this marvel of medieval construction. You feel utterly insignificant on purpose, feeling weak and in presence of something much larger is an easy way to more faith, a truth valid for all humans across all time.
But to me, despite all of this, there was a lot of sadness in that experience - because you know how desperately poor common folks were, how instead of building such status mega symbol they could have done some proper good. But not for church of that era, it was busy fighting for power and money of that world and trying to show how above everybody else they were.
You can see miniature scale of this in literally every (also non-) older European village or town - religious buildings have received by far the most funding and care, sometimes overshadowing kings castles themselves. Cathedrals were always built to impress masses, and this one is just on top of the game, by huge margin for good reasons I believe.
Totally agree.
I was there two weeks ago. The tour guide took us through a route that bypassed the longer lines and through some underground areas—culminating in an entrance that completely blew my mind. I never realized how huge the interior was until I stepped in and saw it firsthand. There are few things in my life that completely took my breath away, this ranks in the top 5 for sure.
