Oh yes, had a Google. What a beautiful interior.
I discovered the inside by chance once when riding the bike - on a bike easy to stop for anything of course.
I sometimes think I have a sort of sixth sense vibe detector or something - I had ridden past it lots of times and had the vague feeling that there was something particular about it.
not sure I'd use the word beautiful to be honest - definitely striking though - gives you a real insight into the minds of earlier folk and the way the church terrorised them/kept them in line.
for anyone interested in seeing it, you can also get to it by London Transport if you are prepared for a bit of a walk - and Farthing Down is wonderful in itself.
