Istria Historical & Maritime Museum Pula

Since ancient times the 34m hill at the centre of Pula's old town has been fortified. The current star-shaped fortress was built by the Venetians in the 1630s. It's now a moody backdrop to exhibitions on an eclectic range of historic themes (the antifascist struggle and a local boxing club at the time of research), but it's worth visiting for the views alone. Hidden around the back of the castle are the ruins of a small ancient Roman theatre.
