Senglea (Maltese: L-Isla) is a fortified city in the east of Malta, mainly in the Grand Harbour area. It is one of the Three Cities in the east of Malta, the other two being Cospicua and Vittoriosa, and has a population of slightly below three thousand people. The city is also called Civitas Invicta, because it managed to resist the Ottoman invasion at the Great Siege of 1565. The proper name is Senglea since the grandmaster who built it, Claude De La Sengle, gave this city a part of his name.
