Austria is a landlocked country of roughly 8.47 million people in Central Europe. It is bordered by the Czech Republic and Germany to the north, Hungary and Slovakia to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The territory of Austria covers 83,855 square kilometres (32,377 sq mi) and has a temperate and alpine climate. Austria's terrain is highly mountainous due to the presence of the Alps; only 32% of the country is below 500 metres (1,640 ft), and its highest point is 3,798 metres (12,461 ft).
