For some, it’s the sheer grandeur and architectural splendor. Strasbourg, Chartres, Cologne or Rouen Cathedrals, with their scale and delicate designs, often stand out.

For others, it’s the spiritual resonance of a place. The Cathedral of Santiago de Compostela has stirred something deeper within, but maybe that was just me. I experienced the same with Lourdes and Le Puy-en-Velay in France because they carried something that felt "sacred" and transformative, not only from the buildings but the actual place.

Then there are those who value historical or religious authority. Cathedrals like St. Peter’s in Rome or the Papal Palace in Avignon have that kind of symbolic weight, and I assume some would favor them over the more "profane" work of Gaudi.
