Rouen cathedral in Normandy, France

I visited friends here – they’d gone to university here and had a history of living in this city that they wanted to share with me.  I got to see the famous Rouen cathedral that Monet painted.  I recall reading a story that Monet painted Rouen cathedral over and over again at a time when his eyesight was failing and he was only able to see everything in varying shades of yellow, red and purple.  He painted lots of variations of Rouen cathedral but burnt many of them.  Only a few copies survive in the world now.
