Austria is bordered to the north by the Czech Republic, to the northeast by Slovakia, to the east by Hungary, to the south by Slovenia, to the southwest by Italy, to the west by Switzerland and Liechtenstein, and to the northwest by Germany. It extends roughly 360 miles (580 km) from east to west. Austria, as a unified state, emerged from the remnants of the Eastern and Hungarian March at the end of the first millennium, first as a frontier march of the Holy Roman Empire, it then developed into a duchy in 1156, and was made an Archduchy in 1453. Austria has the 13th highest nominal GDP per capita with high standards of living. The area that is now Austria was settled in pre-Roman times by various Celtic tribes, having been the core of the Hallstatt culture by the 6th century BC. Austria, largely mountainous landlocked country of south-central Europe. Together with Switzerland, it forms what has been characterized as the neutral core of Europe, notwithstanding Austria’s full membership since 1995 in the supranational European Union (EU). A great part of Austria’s prominence can be attributed to its geographic position. It is at the centre of European traffic between east and west along the great Danubian trade route and between north and south through the magnificent Alpine passes, thus embedding the country. Austria is a land of lakes, many of them a legacy of the Pleistocene Epoch, during which glacial erosion scooped out mountain lakes in the central Alpine district, notably around the Salzkammergut. The largest lakes—lying partly in the territory of neighbouring countries—are Lake Constance (Bodensee) in the west and the marshy Neusiedler Lake (Neusiedlersee) in the east.
