Church?
About 40 years ago, when I started college(stop laughing!) I took up with a nice Irish Catholic girl. A lifelong love of architecture was birthed by that connection and being able to visit beautiful churches and cathedrals. My father and I had quite the religious experience in Leipzig, Germany on a business trip. We got to visit a few churches/cathedrals where Protestantism began. For Dad it was as significant as a trip to Jerusalem. For me, it was the same experience as visiting F.L. Wright's Taliesin West. An intense experience in spaces devoted to uplifting human beings.
As such, whenever I get to feeling the need for inspiration, I go to a cathedral. Or a monastery. The "feeling" is what I need. I liken it to being deep in the woods with only myself and my thoughts.
