In the Great Siege of 1565, Fort Saint Elmo fell to the Ottomans, but the Order eventually won the siege with the help of Sicilian reinforcements. The victorious Grand Master, Jean de Valette, immediately set out to build a new fortified city on the Sciberras Peninsula to fortify the Order's position in Malta and bind the Knights to the island. The city took his name and was called ''La Valletta''.
