Founded in 1565 by the Order of St John as a refuge for soldiers returning from the Crusades, Valletta is now the capital of Malta and a piece of living history. With an unsurpassed collection of original Baroque architecture, fortified city walls overlooking the Mediterranean Sea, and the spectacular Co-Cathedral of St John, which features intricately carved stone vaults and a famed painting by Caravaggio, it is no wonder that this smallest of European capital cities is a world heritage site.
