Valletta (/vəˈlɛtə/, Maltese: il-Belt Valletta, Maltese pronunciation: [vɐˈlːɛtːɐ]) is the capital city of Malta. Located in the South Eastern Region of the main island, between Marsamxett Harbour to the west and the Grand Harbour to the east, its population in 2014 was 6,444, while the metropolitan area around it has a population of 393,938. Valletta is second only to Nicosia as the southernmost capital of Europe, and at just 0.61 square kilometres (61 ha), it is the European Union’s smallest capital city.
Valletta’s 16th-century buildings were constructed by the Knights Hospitaller. The city was named after Jean Parisot de Valette, who succeeded in defending the island from an Ottoman invasion in 1565. The city is Baroque in character, with elements of Mannerist, Neo-Classical and Modern architecture, though the Second World War left major scars on the city, particularly the destruction of the Royal Opera House. The city was officially recognised as a World Heritage Site by UNESCO in 1980.
The city’s fortifications, consisting of bastions, curtains and cavaliers, along with the beauty of its Baroque palaces, gardens and churches, led the ruling houses of Europe to give the city its nickname Superbissima– Latin for “Proudest”. Wikipedia
