Top things to do in Malta
"Guarding Marsamxett and Grand Harbours is Fort St Elmo, named after the patron saint of mariners. The fort was built by the Knights in 1552 in just four months to guard the harbours on either side of the Sceberras Peninsula, and bore the brunt of Turkish arms during 1565's Great Siege. After restoration, the fort reopened in 2015, and now contains the National War Museum, which covers Malta's wartime history including the Great Siege and the country's ordeal during WWII."
