I am not religious, or rather no longer. However, the UK's churches are an enormous resource - historical, cultural, architectural etc etc.I take great pleasure in visiting a small rural medieval church and imagining what it has seen. See this marvellous collection of photos of UK churches by Mark Fairhurst.
"I went back a few hundred years and imagined being a medieval peasant. To visit one of these huge cathedrals for the very first time, it must have looked like something had landed from another planet - totally out of this world."
