Bratislava, historically known as Preßburg (Pressburg), is the capital and largest city of Slovakia. Officially, the population of the city is about 475,000; however, it is estimated to be more than 660,000—approximately 140% of the official figures. Bratislava is in southwestern Slovakia at the foot of the Little Carpathians, occupying both banks of the River Danube and the left bank of the River Morava. Bordering Austria and Hungary, it is the only national capital to border two sovereign states.
