This is truely a city of stunning mosaics, and all but one of the 8 sites listed in this WHS is decorated with the most colourful of mosaic art. By contrast the Mausoleum of Theodoric has a few faded frescoes and a red stone hip bath. Why was this included in the WHS?
The two churches of St Appolina, one in Ravenna, the other in Classe were for me the most outstanding. I travelled between the two by bus #4 and by train.
