Birgu was the site of major battles between the Knights and the Ottoman Empire during the Great Siege of Malta in 1565. After four months of successful defence by the Knights, the city was almost captured by the Ottoman army in August, but was recaptured by the Knights under Grand Master Jean Parisot de Valette. Reinforcements from Sicily arrived a month later, and the siege was abandoned by the Ottomans. After this, a new capital city was built on Mount Sceberras, bearing the name Valletta. In 1571, the Knights transferred their convent and seat to the new capital and Birgu lost some of its importance. Despite this, after the Siege, Birgu was given the title "Città Vittoriosa", Italian for "victorious city".
