town, one of the Three Cities (the others being Cospicua and Vittoriosa) of eastern Malta. Senglea lies on a small, narrow peninsula between French Creek to the west and Dockyard Creek to the east, just south of Valletta across Grand Harbour. In 1552 a fort was built on the peninsula by the Knights of Malta (Hospitallers), and the town was founded in 1554 by the Knights' grand master Claude de la Sengle. Subsequently fortified, it played an important role during the Great Siege of Malta in 1565, when it suffered heavy damage. Extensive redevelopment and the establishment of commercial and shipbuilding facilities made it the most prosperous of the Three Cities in the 18th century. It was almost completely destroyed in World War II air raids. Its ship-repair yards have since been rebuilt and provide a major source of employment. Pop. (1999) 3,536.
