The impressive façade was visible from even the harbor. Today just one foundation wall remains.
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.
It has two floors, and most of the exhibits are on the second, past the big stairs. There are also gardens with statues and mosaic. Hard to find at the end of the garden is a several floor Ottoman home under reconstruction that is partially open. The museum operates a tour of the city walls Tuesdays and Saturdays at 08:00 leaving from the Palace of the Grand Masters. Visitors are simply allowed up on the walls to walk along the top of them at their own pace. This walk offers views of the town not otherwise available and is the best way to get an idea of the size of the town and the variety of its architecture.It is not guided.
Museum of Decorative Art
Very small museum with only one room.
