Senglea (Isla) is the one of the "Three Cities" which involves the dockyards. This was the part of the Grand Harbour which was the center of British Naval ship maintenance and suffered consequently heavy damage during World War II. A lot if the region was abandoned and people were forced to move to the more rural areas, causing a lot of tension in the Maltese population which sometimes is still funnily present in some respect. Those who remained in the Grand Harbour region, specially in the South, had to live in ruins. The dock yards became a major employer, and rebuilding started. With the independence of Malta from British occupation (some call it "protection") this became the heartland of the Labour Party. Today, I personally think it is one of the most beautiful places on Malta. Sure, there is still a lot to do. But I rather see the potential than the deficits.
