And what's special about this? I often enter churches when I'm travelling. In many cases, there is nothing particular to see, but some churches have that extra. Notre Dame is world famous, so it must be in that second category, or? No. Maybe I missed the important part. Maybe there were just too many people. Maybe I just wasn't in the mood. But I have definitely seen more interesting churches than this one – and I would see one more later the same day.
