I suppose saying that what we liked most was sitting on the steps singing ' Feed the birds' from Julie Andrews film Mary Poppins might seem nutty but we loved the movie and being in the exact place it was filmed was very nice. The street in front of the Cathedral is interesting and the Cathedral itself is interesting if you use the audio tour supplied. There is a lot to listen to but they provide chairs so you can sit down to take it in. Having been to Rome we had seen cathedrals that were more spectacular than this one but it was still a nice visit and we learned a lot. Best kept for a rainy day as it is a good wet day activity.
