I reviewed a a Ravenna travel book and tripadvisor and it appears that altough the Naional Museum is closed on Monday, all the other sites such as San Vitale, Galla Placidia, St. Apollinare Nuovo and Classe, Neonian Baptistry, Dante's tomb and Theodoric mausolum are ALL OPEN ON MONDAY. Is this correct or am I misreading the guidebook? It also appears that on a SUNDAY EVERYTHING IS OPEN. Am I misreading the guidebook? Thanks, gang.
