Aurajoki is a river in south-western Finland. It originates in Oripää, and flows through Pöytyä, Aura, Lieto, and ultimately the city of Turku before discharging into the Archipelago Sea. The total length of the river is about 70 kilometres (43 mi), and it contains eleven rapids, the biggest of which is Nautelankoski at Lieto. The reserve tap water for Turku Region is drawn from Aurajoki, the city's secondary waterworks being situated by the Halinen rapids.
Etymology
There several theories for the origin of the name Aura. The most widely accepted explanation traces the name back to an Old Scandinavian word, *āþra, 'waterway'. This word corresponds to the modern Swedish åder, which means 'vein' or 'artery' but can also refer to a watercourse. Another prominent theory connects the name to the Finnish word aura, 'plough', which may have been a descriptive name for one of the rapids in the river. Other theories have also been put forward over the years. These include a connection to the Old West Norse word aurr, meaning 'gravel' or 'sand'; ==Gallery==
