Malta - City of Valletta

"The capital of Malta is inextricably linked to the history of the military and charitable Order of St John of Jerusalem. It was ruled successively by the Phoenicians, Greeks, Carthaginians, Romans, Byzantines, Arabs and the Order of the Knights of St John. Valletta’s 320 monuments, all within an area of 55 ha, make it one of the most concentrated historic areas in the world."
