Attached to San Vitale is the National Museum. I must apologize for the small number of pictures below; having been to both San Vitale and Galla Placidia before this, I was not very fresh and tired of looking. The pictures below make it look as if the museum has only ancient things, but that's not so. They have artworks right up to the present day. Here are some ancient things, many of them quite small.
I am skipping over a lot of interesting stuff that I was too tired to photograph. The contemporary art section (always of interest to me) had a number of works by artists unknown to me, some of which relate to the 'mosaic culture' of Ravenna.
