Senglea (Maltese: L-Isla [ˈlɪslɐ]), also known by its title Città Invicta (or Civitas Invicta), is a fortified city in the South Eastern Region of Malta. It is one of the Three Cities in the Grand Harbour area, the other two being Cospicua and Vittoriosa, and has a population of slightly below three thousand people. The city's title Città Invicta was given because it managed to resist the Ottoman invasion at the Great Siege of Malta in 1565. The name is Senglea since the grandmaster who built it, Claude de la Sengle, gave this city a part of his name.
