The country covers just over 316 km2 (122 sq mi), with a population of just under 450,000,making it one of the world's smallest and most densely populated countries. The capital of Malta is Valletta, which at 0.8 km2, is the smallest national capital in the European Union. Malta has two official languages: Maltese and English.
