This is Stunning! The colours used on the Fresco's seem to be alive and it feels like it has just been painted. This is the best presented 'room' I have seen so far in Italy, and I've seen quite a few. Take the opportunity to sit around the edges and look at the detail.
NOT TO BE MISSED
Just be careful as this is part of the main Cathedral and while it is signposted it would be easy to miss.
