There are magnificent things to see in Ravenna; photographs are pointless in conveying the scale and intricacy in the craft you may find there. I can only share tiny things I saw next to things that sustain open-mouthed staring for several minutes.
Ravenna has grand mosaics in the true sense of grand but at some point I stopped looking. I saw bamboo flapping against the top of a high wall. Of course I found a gap to spy through and was rewarded with a daffodil garden and six white peacocks just before it got too dark to see.
We only just made our train back and then decided to take the next one anyway and spend an hour exploring the joy that is a supermarket in a foreign place.
Visit Ravenna, the city bikes are free and the mosaics are heavy on gold (and old).
(I found sugar-paper confetti on the pavement outside the train station)
