can be split into outside, courtyard, outside wall, first floor and second floor. Open in season till 20:00, entry is €6. A combined ticket at €10 includes the Archeological museum, The Decorative Arts Collection and Our Lady of the Castle church with orthodox art and a few frescoes. The outside wall surrounding the old town is a separate ticket at an additional €3. The ticket line may take 30 minutes so get all your tickets at once. The city wall is only open from 12:00 to 15:00.The first floor (photos prohibited) contains some artifacts of Ancient Rhodes but is closed. In its absence, the entrance fee is entirely not worth it. The Archaeological Museum offers more selection and allows photos. Second floor has a variety of later "artifacts" such as mosaics from Kos and other odd bits and bobs, but it has almost no descriptions (probably to force people to wait for a tour guide). The Palace of the Grand Masters was demolished by a gunpowder explosion in 1856 and reconstructed by the Italians as a summer residence for Mussolini in 1940. This knowledge (that this isn't actually an authentic swords and knights castle and is instead basically a souped up country mansion) somewhat lessens the excitement. Take your photos outside, and come back to look inside when the ground floor exhibitions on Rhodes are open.
Museum of Decorative Art
Very small museum with only one room.
