I haven’t travelled much, relatively speaking. Personally the most impressive cathedral I knew of was St. John the Divine in New York City, but that was mostly due to the fact it was still under construction but already the largest cathedral in the world. And it had a section with a significant bent towards artists, which appealed to me greatly when I first set foot in it.
However, I think that’s going to have to take a back seat to this: Justo Gallego MartÃnez’ cathedral, dedicated to Nuestra Señora del Pilar, Madre de Jesús. What makes it so special? He’s building it himself. All of it. Go and read the article. It’s amazing.
The really shitty part of all this is that he’s seventy, so he probably won’t be able to finish it, and chances are the whole place will get torn down once he passes on. We can only hope somebody snags it instead and dedicates it to the human spirit and our need to create. Because that’s what it’s really a testament to.
